可能拥有美军未使用的先进技术 专家:中国气球或由人工智能引导

0

作者:  来源:联合早报

中国气球出现在美国上空,引起诸多猜测。美国专家星期五(2月3日)指出,五角大楼在美国境内发现的中国监视气球,可能是由先进的人工智能技术引导的。

美国战略智库“马拉松倡议”(Marathon Initiative)的间谍气球专家威廉·金对法新社说,气球是一种有用的观察手段,很难被击落。一名官员告诉美国广播公司新闻台,这个中国气球大概有三辆公共巴士那么大。

威廉说,中国气球看起来很像气象气球,却具备一些特点,比如它有一个相当大的“有效载荷”(payload),放置用于制导和收集信息的电子设备,并由大型太阳能电池板供电。它也似乎拥有美国军方尚未投入使用的先进转向技术。

他说,近期人工智能的进步,让气球能够通过读取周围空气的变化来调整高度,前往它的目的地。这过程中,它也可能需要接收基地无线电通信的引导。

他指出,卫星越来越容易受到来自地球和太空的攻击,气球具有明显优势。此外,气球可以轻易避开雷达侦察。与间谍机构利用不断绕轨道运行的卫星摄像相比,气球可以在监视目标上方保持位置停留好几个月。

至于中国气球会不会是意外进入美国领空,威廉认为这是可能的。这类气球通常在6万5000英尺至10万英尺的高度运行,而境内发现的气球高度约4万6000英尺。“这个高度肯定有点低……如果你想让它更难被发现、更难被击落,那就应该在更高的高度运行。”

他指出,要击落气球不容易,即使被射中,气体也是非常缓慢地泄漏。1998年加拿大派出战斗机试图击落一个气象气球,结果气球六天后才落地。

熟知内情的专家说,监视气球可能是中国用来观察美方军事地点或测试美国的反侦察能力的。

分析员:气球肯定被发现显示北京明目张胆

亚洲协会政策研究所中国分析中心的高级研究员莫里斯说:“由于它可能没有任何官方标记,北京可能认为它可以打‘似是而非’的牌。”莫里斯曾担任国防部长办公室中国事务主任。

不过有分析员认为,使用肯定会被发现的气球,显示北京的明目张胆。

哈德逊研究所的亚太安全问题负责人克罗宁说,北京的卫星一直在监视美国洲际弹道导弹场和其他战略基地,使用气球似乎是多余的。他认为中方可能是想在美国国务卿布林肯会见中国官方之际,以心理战术吸引美方注意,从而发出一个信息——在紧张局势失控之前,美国应该放弃对台湾的支持和在亚洲推进防御活动。”

也有分析指出,使用出乎意料出现的气球会让美国没有时间隐藏希望保密的资产,而且监视气球通常有红外传感器,能提供与卫星不同的信息。

刘德海:中美不信任 布林肯想要什么

0

作者:黄筱筠  来源:中评社

美国务卿布林肯暂缓访华,政治大学外交学系兼任教授刘德海接受中评社访问指出,美国目前抗中氛围越来越强,民主党与共和党两党角力,加上中美之间暗潮汹涌,整体情势复杂,让中美情势更加难以预料,加上互相不信任,发生气球事件后,布林肯脸上挂不住才说要暂缓。但拜登若要寻求连任,还是要靠经济牌,他认为,布林肯之后还是会访中。

至于布林肯访华暂缓之后会不会取消?刘德海认为,布林肯还是会去。第一要应付共和党,如果没事后还是要去北京,否则民主党会处于挨打地位;第二,拜登拼命打经济牌就是要选连任,之前原本要攻击特朗普机密文件,但是拜登自己家也被搜出来机密文件,这样就无法这样对付特朗普。必须要拿出“经济牌”争取连任。拜登如果要经济利益,还是中国能给的最多,拜登一定希望中美签订投资协定,只要一签署,美国华尔街股市一定高涨。

美国国务卿布林肯原订5日华访,为美国总统拜登与习近平今年会面铺路,但是在2日传出中国气球飘越美国蒙大拿州上空后,美国国务院3日表示,经跨部门与国会讨论后,目前并非布林肯访问中国的适当时机,决定延迟访中。

刘德海对中评社分析,布林肯访中暂缓,加上美国众议院议长麦卡锡是否访台等议题,都可以观察到美国抗中气氛越来越强,民主党与共和党相互竞争抗中不是好现象。麦卡锡一下子传出要访问台湾,一下子又说目前无访台计划等,两党积极抗中,争取成为2024候选人。

他表示,这时候出现气球事件,对美国来说是第二次世界大战之后碰到尴尬局面,过去冷战时期发生古巴危机,都没有发生过这样的事情,对美国来说非常尴尬,美方也担心气球伤害无法预测,可能担心里面有毒气、细菌等,而不敢打下来。中美之间互相不信任,对于这颗气球,打也不是,不打也不是。

他指出,过去长期都是美国干扰别人,像是来南海骚扰一下,直到2001年南海侦察机迫降事件,美国才比较节制。当时美国第一次碰到有人可以拦截侦查机,中国现在这样动作是反制美国,不管有意、无意,让美国头一次面对被人家骚扰情形,过去骚扰别人没有事,现在竟然有对手会这样做,美国当然尴尬,布林肯脸上挂不住,才会宣布暂缓访中。

刘德海表示,除了中美之间不信任,美国内部两党也斗来斗去,像是传出麦卡锡说要访台等传闻都是,中国方面当然不高兴,布林肯说要访中,却又传出麦卡锡访台,那是什么意思?美国内部暗潮汹涌,中美之间也暗潮汹涌。

刘德海说,布林肯访中是要改善关系?还是威胁要什么东西吗?还是去中国示威吗?中国也感觉不舒服,美国做了一堆负面动作,却要中国正面回应,怎么可能。

至于今年“习拜会”还能再度举行吗?他表示,还是有可能,双边合则两利,现在大家共同问题都是经济问题,大家是在上桌前,拿出自己筹码,互相威胁彼此,获得更多的利益,美国更需要中国,布林肯只是暂缓访中,最后还是会去中国访问,除非拜登不想连任,否则一定要拿出选民支持的东西。

麦卡锡说目前无访问台湾计划,之后会有变化?他表示,麦卡锡过去曾经说过要访台必须要实现,最重要是立威,因为前议长佩洛西都访台了,麦卡锡要告诉大家他也抗中,也要为了下一个共和党大选人物造势,就是特朗普了。

刘德海认为,“拜登政府一个头三个大”,一个面对中国问题;第二要面对共和党众议院挑战;还有未来争取连任的问题。现在事情扯在一起,因为美国内部债务上限规模修法的问题,是两党角力的地方。

若要拉抬特朗普声势,麦卡锡访台可能性提高?刘德海表示,访台比较像是麦卡锡自己的看法,特朗普虽抗中,但是语调抗中,真正目的是要经济利益,特朗普可能也不是很赞成麦卡锡访台,特朗普不赞成麦卡锡把问题弄得更严重,只要麦卡锡访台那问题就真的严重。未来特朗普若当选也要跟中国互动。

刘德海指出,若麦卡锡访台,可能来的时间点是4月或是8月,是美国众议院休会时间,祗有休会时间麦卡锡可能访台,会期间可能性较低,但麦卡锡还是看整体情势变化做出调整。

他表示,麦卡锡日前受访说目前没有访台计划,可能是私下与拜登有合作。两人之前针对举债上限,在白宫谈了一次,好像蛮正面,可能把问题解决。若问题可以解决,台面下应该是互动过了,拜登不希望中美关系太僵,私下可能希望麦卡锡不要去台湾。

布林肯借题发挥推迟访华为哪般?

0

作者:余东晖  来源:中评社

美方以中国高空气球出现在美国领空,当前访华条件不合适为由,推迟了原定于5日开始的国务卿布林肯的访华行程。有美国专家认为,面对国内强大的政治压力,布林肯实际上是借题发挥,暂时躲过一次本不被大家看好的访问。

中方表示,这个民用高空气球是因为不可抗力原因而飘到美国上空,并对此表示遗憾,但这个气球被美方定性为“侦察气球”,美国媒体更是大肆渲染“间谍气球”。美国智库战略与国际研究中心高级研究员刘易斯(James Lewis)认为,以气球来收集情报是上世纪五十年代的落后技术,有许多限制条件,中方不太可能利用气球来美国本土上空进行侦察。

五角大楼确认这个气球目前不对地面和飞航安全构成威胁,国防官员也确认这个气球无法收集重要情报。正因如此,美国军方“强烈建议”不射落这个气球,而是继续监督其在美国中部上空飘移。然而这个意外事件这两天被美方炒作成头号新闻,将这个被美国称为“以往时常发生”的事件渲染成了中国进入美国领空进行侦察活动的爆炸性新闻。

布林肯指责中方“违反美国主权和国际法,削弱了此行的目的”,称在访问前夕发生这样的事情是“不负责任的、不可接受的”;美国务院高级官员说,这一事件“将大大缩小”此行的议程。因而美方认为布林肯此时访华“条件不合适”,要等“条件允许时”再访华。美国官方不愿意说明什么叫“条件允许”,布林肯只是说“第一步要让这个气球离开美国空域”。

此次访问被认为是跟进两国领导人去年11月巴厘岛峰会达成的加强高层沟通的共识,但外界对此访取得成果和实现突破不表乐观,包括在被认为最重要的台湾问题、俄乌战争、芬太尼等议题上,专家普遍对取得进展不抱期待。

美国巴克内尔大学教授朱志群对中评社表示,双方在台湾问题上不可能有真正的成果,更可能是各说各话,最多在台湾问题上稍微降温。即便如此,如果麦卡锡4月份访台的话,所有的努力将付诸东流。

观察家注意到,虽然美国媒体早就透露布林肯将于2月5日和6日访问中国,但一直到2月3日,两国官方都没有正式宣布访问行程,反而在2日晚间爆出气球事件,说明双方本来就有许多议程尚未达成共识,布林肯能否如美方媒体放风的如期成行都要打上问号。

即便在原定访问行程临近之时,美方也并未放慢在科技上围堵中国,在军事上威慑中国的脚步。美国联手日本和荷兰加入芯片光刻机的对华禁运,拉拢印度在供应链上对华脱钩,在菲律宾增加4个军事基地等,美军前印太司令访台等动作不断,并没有显示美方打算通过此次访问,寻求缓和对华关系的政策。

美国国会鹰派将此访当作美国当面对华施压的机会,多位美国议员致信拜登政府,要求他们对华表现强硬。《华盛顿邮报》情报和国家安全记者哈里斯(Shane Harris)说,白宫因被认为对中国表现得过于和缓而受到来自共和党人的巨大压力。布林肯此行可能会引起共和党议员的嚎叫。

在这种大背景下去落实元首共识,朱志群分析,布林肯访华意愿本来就不高,因为不管是布林肯访华是不欢而散、空手而归,还是寻求妥协、达成共识,他回来后都会挨骂。这个访问本来象征意义就是大于实际意义,没有什么值得特别期待。

美利坚大学国际关系学院教授赵全胜也对中评社表示,如果双方没有准备好,氛围不好的话,那推迟此次访问也罢,省得到时候吵起来,回来不好交代。

朱志群说,在布林肯对此访意愿和期待并不高的情况下,气球事件发生后,如何处理完全在美方一念之间。你可以把它炒作成一个很大的危机事件,来推迟访问;你也可以把它视为一个意外的事故,继续去访问,不受影响。事实上,美方决定还是要把它放大,去炒作。也就是说,气球事件为布林肯不愿访华提供了一个很好的借口。

观察家相信,这个气球从中国经阿留申群岛、阿拉斯加、加拿大一路向东向北飘行,直到进入美国有洲际导弹发射井的蒙大拿州,美方才突然拿这个大作文章,又不愿将其击落,显然有刻意渲染“中国威胁”,试图掌握话语主动权的意图。

朱志群说,布林肯现在等于把这个球踢到中方了,他可能无限期推迟,估计可能要推迟到麦卡锡访台以后,要看中方的反应如何,再决定他什么时候再去。

《纽约时报》指出:“拜登政府官员最初的公开反应突显了与北京的关系变得多么脆弱和微妙,甚至只是因为一个气球。”事件披露后,美国国会对华鹰派们抓住机会,掀起了鞭挞中国的高潮。拜登政府专门就此事对国会两院领袖和情报军事委员会负责人组成的“八人帮”进行汇报。

朱志群指出,此次事件也说明美中双方互信实在不足,现在要保持高层交流都有些困难,气球事件一下子让这个关系马上又跌回去,要重新开始建立一些基本的互信。这是一个很大的麻烦。

赵全胜对中评社指出,这个事件表明,双方都有要需要解决的问题,更需要聚到一起,所以这个访问恐怕还要尽早恢复。此次事件也更加说明沟通的重要性,今后的沟通应该加强,而不是减少。

美国官方在推迟访问做出强势姿态的同时,也再三强调,注意到中方表达的遗憾,今后将继续保持与中方的外交接触和沟通渠道开放,负责任地管控美中这个最复杂、最具后果的竞争关系。

中国官方的表态也留有一手,只是表示坚决反对“美国一些政客、媒体借题发挥,对中国攻击抹黑”,“事实上,中美双方都没有宣布过什么访问,美方发布有关消息是美方自己的事情,我们予以尊重”。

显然,两国官方都不希望此次事件成为两国关系扭头急转直下的转折点。当务之急是美方停止炒作,通过内部沟通与协调,妥善处理。

丁树范:美中谈的议题没处理好布林肯缓访华

0

作者:张嘉文  来源:中评社

美国国务院3日发布国务卿布林肯(Antony Blinken)访中行程暂缓。政治大学东亚研究所名誉教授丁树范接受中评社访问表示,美中关系不好大家都知道,这次似乎主因是先遣人员事前安排的议题,彼此没有讲好、处理好,美国才会藉由气球事件暂缓布林肯的出访行程。

丁树范认为,因为美中之间的结构性问题原本就已经很坏了,这次事件只能说是在很坏关系中的一个访问行程,理论上彼此的关系也不会再坏,因为结构性本身就已经够坏了。

美国国务卿布林肯原订5日访华,为中美元首今年会面铺路,但2日传出中国气球飘越美国蒙大拿州上空后,美国国务院3日表示,经跨部门与国会讨论后,目前并非布林肯访问中国的适当时机,决定延迟访中。

丁树范接受中评社访问时表示,他认为暂缓主因应该是彼此的先遣人员在要谈什么议题上,没有处理好,所以让美方决定乾脆布林肯就不去北京了。

至于暂缓后续是否还机会恢复双方的会谈?丁树范说,这不一定,目前美方说法是暂缓,或许之后布林肯应该还会有机会去北京访问,中美之间的沟通还是会持续进行,沟通不是问题,问题是沟通以后彼此要达成什么成果,这才是问题。

丁树范强调,美中双方高层级官员的会谈,先遣人员譬如美国国务院或者是白宫,有先派成员到北京,就彼此要谈的议题先沟通好,譬如对台问题,或者是美国众议院议长麦卡锡(Kevin McCarthy)如果要访台,彼此要怎么表述等等,这些都需先遣人员处理好,很可能就是彼此在这方面意见很不一致,才会让此次的会谈暂缓。

丁树范表示,总结来说,中美的结构性问题,也并非双方面能坐下来谈一谈见个面,事后发个共同声明,就能马上解决。但如果连这类事情都摆不平,更是连坐下来谈都不可能了。

李大中:中美战略互信严重缺乏 影响两岸

0

作者:张嘉文  来源:中评社

美国国务院3日发布国务卿布林肯(Antony Blinken)访中行程暂缓。淡江大学国际事务与战略研究所副教授李大中表示,这是中美关系一个非常不好的政治讯号,也凸显了目前双方战略互信的缺乏,且不是一天、两天的事情,而是这些年来都很严重,因此很容易因为一些原本可化解的事件,负面效果却变得非常强,两岸关系也会受影响。

李大中说,美方虽然说是访问行程延期,可是这延期就怕后续遥遥无期,好不容易有一个中美可以缓和的机会,现在可能没有了,时机稍纵即逝。

美国国务卿布林肯原订5日访华,为中美元首今年会面铺路,但2日传出中国气球飘越美国蒙大拿州上空后,美国国务院3日表示,经跨部门与国会讨论后,目前并非布林肯访问中国的适当时机,决定延迟访中。

李大中接受中评社访问时对此表示,布林肯的访中行程喊卡,会对去年11月拜习会所达到基础共识,产生一个不好的政治讯号。去年八月佩洛西以众议院议长身分访台后,中美之间很多沟通管道是暂停了,拜习会中有共识要重启,但比较明确的祗有气候变迁问题上有重启沟通。

李大中说,当中美之间制式的管道都是走走停停,原本布林肯访中这个行程就显得很重要,有高度的象征跟实质性,但却因为气球事件就被延迟,背后就反映出目前中美之间的战略互信缺乏非常严重,也反映出目前中美关系的困境。类似事件在美中关系还可以时,负面效应不会像现在这么强,可能比较容易化解。

当美中矛盾加深,接下来的两岸关系就可能会受很大的影响,李大中说,这些都是会互相牵动,而目前这气球事件当然可大可小,当然美国一定会有反应,但假设今天中美之间有共识,或者说双方的关系是处于和缓阶段,可能布林肯的访问行程仍有机会照常进行。

李大中认为,但现在因为美国国会本来就有比较大的质疑中国的声音,都导致气球事件后作用力被放大很多,在这样的美国国内氛围下,即便布林肯本人仍有意愿要访中,也都让他不得不喊卡。

“间谍气球”事件显示中美关系脆弱到无法承受普通打击

0

作者:  来源:联合早报

受访学者分析,“中国间谍气球”事件显示中美日益恶化的关系已脆弱到无法承受一次普通的打击;事件加剧了拜登政府面对的舆论压力,美国下来将更难对中国作出让步。

美国白宫是在去年11月中美两国元首首次面对面会晤后,宣布美国国务卿布林肯将访华。外界原本预计布林肯将推动两国恢复双边高层接触,以便为中美关系设立“防护栏”。

中国人民大学国际关系教授时殷弘此前认为,中美在台湾、半导体高科技等议题上持续对抗,在此背景下,布林肯的访华行程将难以为两国关系带来显著和长远的改善。

时殷弘星期六(2月4日)接受《联合早报》采访时说,很讽刺地,即便是当时这个悲观的预测如今看来都有点乐观。中美日益恶化的关系已脆弱到无法承受一次普通的打击,中美关系要取得“显著和长远的改善”,看来几乎得依靠奇迹出现。

美国将在2024年举行总统选举,各党目前都已积极为选举做准备,国内舆论环境因此变得越来越敏感。

据彭博社报道,美国官方1月28日已侦测到进入美国领空的不明物体,但数日都低调处理事件。复旦大学国际问题研究院常务副院长、美国研究中心主任吴心伯分析,这起事件相信是一场意外,气球没有太大的军事作用,否则美国不会好几天都不采取行动。

吴心伯说,布林肯访华前已经在美国国内受到很大的压力,不少人都在质疑他访华的必要;在气球事件后,他得顺势作出一个姿态,对国内保守派有所交代。

南洋理工大学公共政策与全球事务课程助理教授骆明辉研判,布林肯取消访华行程并不是小题大做,相信没有任何国家会允许他国的军事、间谍或科学设备未经许可地飞入自己的领空。

骆明辉认为,这次事件有可能是中国相关单位协调出现问题,而不是中国刻意要恫吓美国,因为中国数月来持续释放出期待布林肯访华的信号,布林肯延迟访华对中国没有好处。

他指出,中国官方已承认气球属于中国,并表达了遗憾,这有助于解决这段插曲。但不少共和党人抓住机会批评拜登对中国太软弱,在这样的舆论环境下,拜登下来将更难对中国作出让步,这会对整体的中美关系带来一定的影响。

吴心伯和骆明辉都认为,美国不会完全取消布林肯访华行程,至于双方何时能再安排布林肯访华,两人观点不一。

吴心伯认为,布林肯有可能改于2月底成行;骆明辉则预计,拜登政府可能需要至少几个月的时间才会重新安排布林肯访华,但预计会在今年内成行。

What are the US and China saying about the Montana balloon?

0

作者:Graham Webster  来源:作者newsletter

First, from the US side.

  • A ground stop at the airport in Billings, Montana, on Wednesday that seemed to bring this ongoing incident into public view was part of “protective measures” in case the decision was made to shoot down the balloon. They decided not to, because “military commanders” did not believe the risk to life or property on the ground could be sufficiently lowered, a senior DOD official said.

    • GW note: Can you imagine the political and geopolitical hurricane if some rancher family had a big piece of Chinese sensor land on their kid’s bedroom?

  • The balloon has been tracked by US authorities throughout its time over the United States.
    “We have had custody of it the entire time it has been over US airspace, entered the continental United States airspace a couple of days ago,” the DOD official said.

    • GW note: If the phrasing is careful and if the balloon also passed over Alaska, this would suggest it’s been tracked for even longer than “a couple of days.”

  • “Clearly the intent of this balloon is for surveillance,” but it “does not create significant value added over and above what the PRC is likely able to collect through things like satellites in Low Earth Orbit,” said the official.

  • This has been going on for years, including under one or more previous administrations.
    “It is not the first time that you had a balloon of this nature cross over the continental United States. It has happened a handful of other times over the past few years, to include before this administration,” the Defense official said. But, they said, “I will say that the past number of times it did not loiter over the continental United States for an extended period of time. It’s different.”

    • GW note: This appears to anticipate criticism that, if such incidents have been happening, the Biden administration has not made them public or worked to stop them. A partial response is now set up for the White House: that the DOD has said these incidents preceded their watch and anyway lack significant increased surveillance threats.

  • The Defense official appears confident China decided to take a different course.
    “And clearly they’re trying to fly this — this balloon over sensitive sites, one of which was just mentioned, to collect information.” … “And precisely why they made the decision to make this different I think really is a question for them.”

  • Communication with Chinese officials is ongoing.
    The Defense official did not specify whether they contacted PLA officials, but said they’ve engaged through multiple channels including the respective embassies.

In sum, a US defense official said similar events have been happening for several years, did not prevaricate on whether this is for surveillance, and attributed its current course to Chinese intentionality, not drifting off target.

Now, from the Chinese side:

  • The Foreign Ministry spokesperson initially said they would need time to look into the issue before providing an answer.

  • Later, the MFA provided a statement. As is frequently the case, the statement was provided in Chinese and English. As often happens, the MFA’s English translation made choices I might not have made, so I’ll provide my version below. And in this context, it’s worth noting that MFA spokespeople regularly make statements that are verifiably false.

The Chinese-language statement (dated 2023-02-03 21:35)

问:据媒体报道,近日一艘中国无人飞艇出现在美国空域。中方对此有何评论?

答:该飞艇来自中国,属民用性质,用于气象等科研。受西风带影响,且自身控制能力有限,该飞艇严重偏离预定航线。中方对飞艇因不可抗力误入美国表示遗憾。中方将继续同美方保持沟通,妥善处理这次因不可抗力导致的意外情况。

The official English-language translation (dated three minutes earlier)

Q: According to media reports, a Chinese unmanned airship has been spotted in US airspace. Do you have any comment?

A: The airship is from China. It is a civilian airship used for research, mainly meteorological, purposes. Affected by the Westerlies and with limited self-steering capability, the airship deviated far from its planned course. The Chinese side regrets the unintended entry of the airship into US airspace due to force majeure. The Chinese side will continue communicating with the US side and properly handle this unexpected situation caused by force majeure.

Observers have reasonably raised their eyebrows at the vague stated purpose for the balloon. “Used for research, mainly meteorological, purposes” is one reasonable translation of “用于气象等科研”—but it’s not very satisfying to me in capturing the message contained in the Chinese sentence.

For an acute incident like this, the MFA’s skilled English-language experts will have focused on getting the English messaging right, but it’s worth looking at the Chinese for two reasons: first, because that’s the message Chinese readers will get, and second, because despite best efforts to render diplomatic language carefully, such statements are usually deliberated in their home language.

So, here’s my highly-literal translation from the Chinese:

The airship¹ is from China. It is civil-use in nature, used for meteorological, etc., scientific research. Affected by the Westerlies, and with limited self-control capabilities, the airship seriously deviated from its planned course. The Chinese side expresses regret that, due to force majeure,² the airship mistakenly entered the United States. The Chinese side will continue to maintain communication with the US side, to appropriately handle this unexpected situation due to force majeure.

As to the question about civilian use and the type of research claimed?

  • The Chinese text makes clear they are asserting this is not for military use.
    This is not some sneaky effort to use “et cetera” to mask military-strategic surveillance; it’s clear they’re asserting civil 民用 as opposed to military use.

  • Of course, scientific research can have military uses (even if they’re not lying).
    In another era, I spent hundreds of hours on the UN Convention on the Law of the Sea and US and Chinese statements about their own and each other’s conduct at sea. In the maritime domain, sovereign powers over conducting or limiting the conduct of maritime scientific research (MSR) are carefully structured and often contested in international law.

  • At sea, there is a long US-China history of suspicion and disagreement over the limits of “scientific research” that could have military applications.
    I can’t take the time to brush up on all the details to make a crisp explanation, but in general the two sides have disagreed on what constitutes MSR versus military surveillance and therefore on who is allowed to do what and where. Legalities aside, suffice it to say that instruments you might find useful for counting fish stocks in the water column may also have utility in tracking submarines. (I welcome pointers to anyone who is analyzing the present dirigible from an informed aeronautical international law perspective, which I don’t have.)

    • Bonus: Remember when China seized a U.S. “unmanned underwater vehicle” or “glider” in 2016? Well that happened in international waters, not in Chinese-controlled seas.

      A DOD photo showing an underwater “glider” similar to the one the PLA Navy grabbed in 2016.

In sum, there is good reason to be skeptical of the MFA explanation. The DOD is using really confident language about the intelligence community’s assessments, and large-scale civilian scientific research, even if details are not regularly shared, should come with a known research institute and program that, you know, publishes research. But the assertion is that (1) it’s civilian, and (2) its current course is inadvertent.

First thoughts on fallout

1. Secretary Blinken’s postponed China trip is a big deal.

While expectations should not have been high for any breakthroughs, travel by the US Secretary of State to China was a key outcome of the Biden-Xi meeting in November. Coming out of the intense downturn in bilateral ties during the Trump administration and following childish recrimination between the two governments during the pandemic, this was a real opportunity to sustain a stabilizing trend and build toward potentially solving some tractable problems. The visit would not have turned the tide away from a darker bilateral era, but it could have, as was hoped before the November meeting, helped to “build a floor for the relationship.”

There are signs that in the immediate term bilateral ties could face more downward pressure. The new Republican-led House has promised a great deal of noise, at minimum, and perhaps more concrete actions targeting both legitimate and politicized matters regarding China. This may now take place without any counterbalance. And it will certainly include talk of this balloon.

Blinken could have gone anyway, but I think it’s reasonable to speculate that the decision was made that the political optics on the home front would be unacceptable. To counter accusations that the administration was weak and playing nice with an invading force, Blinken would have needed to make even stronger moves than usual to signal that he’s going with a tough face on. (Already, the administration has recently hosted Japanese and Dutch leaders, reportedly securing cooperation on the semiconductor blockade, and Blinken recently spoke to the International Religious Freedom Summit, criticizing reiterating the charge of genocide “against predominantly Muslim Uyghurs” and drawing Chinese official condemnation.) Even if he had gone ahead with it, any even modest outcomes would be under a cloud, so there’s a pragmatic diplomatic reason to delay, in addition to the political optics.

2. If the balloon incursion was intentional, it may not be possible to figure out whose intention it was.

Let’s presume for the sake of argument that the US assertion that the balloon was intentionally sent and is for surveillance purposes, not meteorological research, is correct. If so, who sent it? Did whoever sent it do so with the intention of keeping the US side nervous before Blinken’s trip? And who knew?

In 2011, China’s military conducted a stealth fighter test flight while US Secretary of Defense Bob Gates was visiting Beijing. NYT reported at the time: “A senior American defense official said that when Mr. Gates asked Mr. Hu to discuss the test it was evident to the Americans that the Chinese leader and his top civilian advisers were startled by the query and were unprepared to answer him.” “The civilian leadership seemed surprised by the test,” Gates said.

Was Xi Jinping aware of the balloon’s course? Was he in favor of it? Is he livid? We may literally never find out, but if Xi wanted to send a signal that this was someone acting out of turn, I can imagine it would be hard to do so without also revealing division between his personalized leadership and the military, which is broadly understood to be the bottom line guaranteeing his power.

3. If the balloon really was, as the MFA claims, for meteorological research, keeping this and any broader such program secret from the Americans makes broader climate cooperation harder.

Why would they hide scientific research that they could reasonably assume foreign strategic defense forces would notice? If it was scientific research, however, it should be possible to be fairly convincing about this by releasing a good deal of verifiable data.

4. If the balloon was, as the DOD believes, for surveillance purposes, suggesting it was for climate science will make everyone even more suspicious of China in climate cooperation.

And that’s really unfortunate.

From China to Big Sky: The Balloon That Unnerved the White House

Star gazing is nothing unusual in Montana, where skies go on forever. But as Chase Doak left work on a Wednesday and looked up on a cold winter day he saw a mysterious round white object that was clearly neither the moon or a star.

He began to film something that could come straight out of a movie where science fiction meets the Wild West. Within 48 hours the strange thing that went on to confound the residents of Billings was revealed to be a suspected Chinese surveillance balloon.

“Not gonna lie,” tweeted Doak as his video went viral. “First, I thought this was a #ufo. Then, I thought it was @elonmusk in a Wizard of Oz cosplay scenario. But it was just a run-of-the mill Chinese spy balloon!”

Its journey across the ocean has gripped the world’s attention and forced the top US diplomat to cancel his trip to Beijing. Its fate, as it wafts 10 miles above ground, remains uncertain — as do the delicate relations between two superpowers grasping for ways to deescalate tensions and get talks back on track.

""

This account of how a balloon burst diplomacy just as Secretary of State Antony Blinken was set to travel to China and meet with President Xi Jinping is based on conversations with several officials briefed on the matter who asked to stay anonymous to discuss intelligence matters.

As it turns out, US authorities were aware the unidentified object that had entered American airspace on Jan. 28, that had then left and re-entered over North Idaho on Tuesday. But with such a high-profile trip at stake, keeping it on the down-low was key.

By the time the thing became visible in Montana, President Joe Biden had already been briefed and the White House was scrambling to decide whether to blast it from the sky.

The gravity of the situation was only exacerbated by Montana being home to Malmstrom Air Force Base, which houses a large portion of the US’s Minuteman intercontinental ballistic missiles.

The Biden administration knew it had to exercise extreme caution especially in what was a heated political environment ahead of 2024 elections, with Republicans agitating on which party could strike a harder or tougher line on China.

As the balloon continued to hover over the Big Sky state on Wednesday, Biden huddled with his national security team to receive a detailed briefing on the balloon. The president argued for shooting the object down, but was urged against doing so by his most senior military advisors.

Secretary of Defense Lloyd Austin and Chairman of the Joint Chiefs of Staff Mark A. Milley insisted that such a move would put civilians at risk, people familiar with the discussions said.

The president ultimately decided to let the balloon continue on its way as the US sought answers from the Chinese embassy in Washington, but they struggled to obtain satisfactory responses. US officials said they were baffled by China, which itself appeared to be caught off-guard by the bizarre incident.

For now, the White House opted not to inform the American public. Events, however, soon forced Biden’s hand.

On Thursday afternoon, the Billings Gazette, a local Montana paper, published a photo of the balloon – meaning it was only a matter of time until national media would pick up on the report and the Biden administration would have to face questions.

The pace of discussions in the White House quickened.

In a call starting at 5:15pm on Thursday, the administration finally went public. That spurred a rush to brief lawmakers on Capitol Hill. The Biden administration will hold a briefing next week for the “Gang of Eight,” a group of lawmakers including the chairs and ranking members of the House and Senate intelligence committees.

In an effort to keep things calm, administration officials stressed this was not the first such incident and that similar activities had been observed over the past several years, including during the prior administration.

The Pentagon’s announcement prompted an outcry from Republicans. Former President Donald Trump posted on his Truth Social website to “shoot down the balloon.” Others, from former Secretary of State Michael Pompeo to Representative Marjorie Taylor Greene, framed the decision not to shoot down the balloon as a sign of weakness by Biden.

The biggest question was how would China respond to all the furore that was unfolding at a rapid pace as Asia was asleep.

After earlier calling on the US to refrain from “hyping” the incident, China finally commented on the balloon directly in a statement Friday morning Washington time, attributing it to a “force majeure” for which it was not responsible.

China said the balloon blew off course and entered US airspace by accident, adding that it is “regretful” over the incident and that the balloon’s purpose was climate research.

Administration officials are privately dismissive of Beijing’s explanation, as are former American intelligence analysts. The official Chinese explanation mirrored a well-worn excuse for aerial espionage.

“I do not know of anyone who constructs a meteorological balloon the size of three school buses,” said Dennis Wilder, the Central Intelligence Agency’s former deputy assistant director for East Asia and the Pacific.

US officials, who had spent hours debating whether Blinken should scrap a long-planned trip to Beijing, finally felt they had no choice but to postpone the first high-level US visit to China in five years. A delay was not a cancellation. It sent a signal that the US had no desire to escalate matters.

The sentiment among those in the room was that the trip wasn’t worth the potential domestic political costs of going, given that Blinken’s talks in China were not expected to yield much in the first place.

Biden’s team worried that the incident would serve as more fodder for Republicans who believed the administration is weak on China, especially if the balloon crashed and hurt someone while Blinken was in Beijing.

“A split screen of a spy satellite over the United States when Secretary Blinken lands in Beijing would not have been tenable,” said Ryan Hass, a senior fellow at the Brookings Institution and a former Director for China, Taiwan and Mongolia on the National Security Council.

Meanwhile, the balloon continued its voyage eastward across the continental US, heading toward Washington. “The balloon is not going away,” said Wilder, the former CIA officer.

The problem, he said, is that “China has no way to take it back so it will drift over the continental US for an unknown time frame before coming down.”

Until then, Americans will keep taking pictures of it and Biden will have to keep defending the decision not to just shoot it down.

US to Postpone Blinken‘s Visit to China Over Its Spy Balloon

作者:Jenny Leonard and Peter Martin  来源:Bloomberg

The Biden administration has decided to postpone Secretary of State Antony Blinken’s upcoming trip to Beijing after detecting a Chinese surveillance balloon that was lingering at high altitude over sensitive nuclear sites in Montana, according two officials.

Blinken was set to have meetings in Beijing early next week in the first such visit by a top US diplomat in five years. But the presence of the balloon — which the Pentagon decided not to shoot down — led officials to decide that going now would send the wrong signal, according to people familiar with the matter who asked not to be identified discussing internal deliberations.

White House and State Department officials didn’t immediately respond to requests for comment.

China took unusually conciliatory steps to smooth over the incident Friday, with the Foreign Ministry saying it was “regretful” that a civilian airship entered US airspace because of forces beyond its control. It said the balloon was conducting climate research.

The balloon was first spotted earlier this week and had been loitering over Montana, home to intercontinental-ballistic-missile silos, a senior Defense Department official said Wednesday. The official said the balloon posed no intelligence threat and such incursions have happened before.

But the Pentagon’s announcement about the balloon on Thursday prompted an outcry from Republican lawmakers, with Representative Mike Gallagher, the chairman of a new House committee meant to highlight the Chinese threat, saying the presence of the balloon “makes clear that the CCP’s recent diplomatic overtures do not represent a substantive change in policy.”

Earlier in the day, Chinese Foreign Ministry spokeswoman Mao Ning cautioned the US against “hyping” the incident. “We have no intention to violate other countries’ sovereignty and airspace,” Mao told a briefing, adding that she hoped “the relevant parties will handle the matter in a cool-headed way.”

Blinken’s trip was set to be the most senior US visit to China since 2018. For the Biden administration, it’s part of an effort to keep the China rivalry from getting worse. For leaders in Beijing, it’s meant to signal China’s emergence from post-coronavirus pandemic lockdown and a desire to reconnect with the rest of the world.

US officials declined to answer several questions about the balloon, including the precise target of its surveillance, its size or other specifications. “It is currently traveling at an altitude well above commercial air traffic and does not present a military or physical threat to people on the ground,” Brigadier General Pat Ryder, a Pentagon spokesman, told reporters Thursday night.

The senior official said the US had raised the balloon issue with China, and the Wall Street Journal reported that the State Department had summoned the Chinese charge d’affaires. Mao sidestepped questions about whether Blinken’s trip was happening, saying she had no information to provide.

Later Thursday, Canada’s defense department said it was tracking “a potential second incident,” without elaborating. The White House declined to comment on the Canadian statement.

It wasn’t the first time a spy balloon had been spotted over US territory, although this one appeared to be staying longer than in past cases. The technology doesn’t offer China any intelligence-gathering capability beyond what its low-orbit satellites already provide, the US official said.

The official declined to say why the US believed the balloon belonged to China, saying only that US had high confidence in the assessment. The Chinese have for decades complained about the US surveillance by ships and spy planes near its territory, leading to occasional confrontations.

Defense Secretary Lloyd Austin convened a meeting of his top advisers while on a trip to the Philippines on Wednesday and informed President Joe Biden. The US defense chief had been in the Philippines as part of a US effort to rally allies and counter what officials believe is China’s increased assertiveness in the South China Sea and toward Taiwan.

Tensions between Washington and Beijing have been running high, with the Biden administration becoming more explicit about its willingness to defend Taiwan in the event of a conflict. Last week, an Air Force general told his staff he believed the US and China would be at war by 2025. China, at the same time, has taken a softer tone, calling for an end to hostile rhetoric.

The Biden administration also briefed staff for the “Gang of Eight,” a group including the chairs and ranking members of the House and Senate intelligence committees, another official said.

Greg Falco, an aerospace expert at Johns Hopkins University, said spy balloons were no better than satellites at getting good imagery, but that it’s possible the Chinese “are using them to intercept” communications.

德语媒体:中国的试探性气球?

0

作者:  来源:德国之声中文网

《南德意志报》发表评论称,北京和华盛顿之间会以各种手段刺探对方的情报,这本是公开的秘密。但中美关系日趋紧张的敏感时刻,如果蒙大拿州上空的气球的确来自中国,性质和后果就大不相同了。这篇题为《中国的试探性气球》的评论写道:

"间谍活动在国与国的交往中司空见惯,中美两国之间当然也不例外。间谍卫星、侦察飞行、高空气球都是常见的间谍手段,中美双方也都在使用上述手段。有鉴于此,如果不考虑两国关系的现状以及当前这一敏感时机,中国有意或无意释放的这枚高空侦察气球,本来并不足以大惊小怪。

数天前,一名美国军界高官发出了中国即将攻打台湾的警告。而去年十月,美国海军作战部长马丁·吉尔迪( Mike Gilday)也曾做出同样的预判。美国国防部长奥斯汀( Lloyd Austin)刚刚同菲律宾就扩大驻军达成协议,而美国国务卿布林肯也即将开始任务艰巨的北京之行。

事实上,北京的确在以惊人的速度扩展其军事影响力,而北京对台湾所表现出的高度自信,更是令人不得不产生不详的预感。鉴于弥漫全球的危机氛围,人们也有理由担心,尽管中国并不具备明显的军事优势,但还是会很快就对台湾发起军事进攻,而不会再等到2027年。欧洲的事态已经令美国无暇他顾,而习近平一言九鼎的权势地位也从未像今天这么稳固。"

评论指出,气球事件可以被看作是一个警告信号,即中美两大超级大国之间的对抗状态随时都有可能陷入失控状态。

"美国各政治阵营对气球事件的反应,也说明了当前这种一触即发的紧张氛围。共和党借机谴责拜登总统忽视了国家安全。同欧洲相比,美国对中国的敌视情绪要根深蒂固得多,中国也一直是重要的选战议题之一。有鉴于此,气球事件还是非常值得高度关注的。在度过了前一段的内政困境之后,习近平究竟会怎么规划自己的势力范围,布林肯将在北京有所体会。"

《每日镜报》发表了台湾政治学者丘琦欣撰写的客座评论。作者认为,中国的确对台湾构成了极大的威胁,但部分西方学者及军界人士有关短期内台海必有一战的断言,却对各方都毫无裨益,更会损害台湾的利益。

"期望布林肯访问北京期间,在台湾问题上能够采取坚决而不过激的立场。既要拒绝以台湾的自由作为交易筹码,也不能过度刺激北京,从而使北京加大对台湾的威胁,甚至以台湾为目标发泄对美国的不满。

而类似于美国高级将领米尼汉(Mike Minihan)在其备忘录中所发表的各类评论,则对缓解事态并无帮助。这样的警告只会让北京的决策者产生这样的印象,即美国军方正在准备因台湾问题同中国开战,他们认为战争已经不能避免。"
