日中因日本首相高市早苗就「台湾有事」的发言而升温的对立，正演变为资讯战：北京主打「日本重回军国主义」叙事，日本则反驳。欧洲成为关键战场：日本国安顾问市川恵一于12月10日与德国对口官员冈特・绍特通话；此前两天（12月8日），中国外长王毅在北京会见德国外长约翰・瓦德富尔，并以「二战结束80年」为基准指责日本未深刻反省历史。德方对外表述同时包含「一个中国」政策未变与「台湾现状只能以和平方式变更」的立场。

媒体战线呈现多方叙事：BBC在报导中国军机以雷达「锁定」日本自卫队战机事件时，同步呈现日中说法；《金融时报》称日本寻求美方更明确支持；德国《法兰克福汇报》指出美国总统唐纳德・川普未正式评论引发日本不满。日本防卫相小泉进次郎于周五与美国防长彼得・赫格塞斯通话，双方同意中方行动不利于地区和平稳定并表达严重关切，但美国国防部发布的声明未提及「雷达事件」。

在亚洲，部分媒体与政府更偏向日本：新加坡《海峡时报》称东南亚不太可能接受「日本再军国化」的叙事；印度媒体几乎每日追踪，将其视为两大亚洲强权冲突风险上升；菲律宾国防部于周五声明「站在日本与志同道合伙伴一边」。市川于12月4日至5日访菲并会见外长与防长；同时，11月20日与12月5日的多篇社论警告台海冲突外溢风险。学者也指出，中方透过资讯管控塑造叙事，并以治安与旅游提醒等讯息加深外界疑虑。

Rising China-Japan tensions after Prime Minister Sanae Takaichi’s Taiwan-contingency remarks are shifting into information warfare: Beijing frames Tokyo as returning to militarism, while Japan pushes back. Europe is a key front: Japan security adviser Keiichi Ichikawa spoke with Germany’s Gunter Sautter on Dec. 10, two days after China’s Wang Yi met German Foreign Minister Johann Wadephul in Beijing. China’s readout invoked “80 years since World War II,” while Germany reaffirmed its One China policy yet stressed Taiwan’s status quo must change only peacefully by agreement.

Coverage reflects competing narratives and uneven U.S. signaling. The BBC reported the alleged radar targeting of Japanese jets with both sides’ claims; the Financial Times said Japan sought a clearer U.S. statement; and Germany’s FAZ noted President Donald Trump had not officially commented, fueling resentment in Japan. On Friday, Japan’s defense minister Shinjiro Koizumi called U.S. Defense Secretary Pete Hegseth; both voiced serious concern about actions raising regional tensions, but the Pentagon’s statement did not mention discussing the radar incident.

In Asia, several outlets and governments lean toward Japan’s account. Singapore’s Straits Times suggested Southeast Asia is unlikely to accept the “militarism” narrative; Indian media has tracked the issue daily as a rising clash risk; and the Philippines’ defense department said on Friday it stands with Japan and “like-minded partners.” Ichikawa visited the Philippines on Dec. 4–5, while editorials dated Nov. 20 and Dec. 5 warned of Taiwan-conflict spillover; experts also point to China’s information control and to travel-safety messaging as amplifiers of doubt about Japan.
