China Warns UN of Military Response if Japan Intervenes in Taiwan Strait
China warns UN that Japanese military intervention in Taiwan Strait would be “act of aggression”.
China has escalated its diplomatic dispute with Japan by sending a formal letter to United Nations Secretary-General Antonio Guterres, warning that any Japanese military intervention in the Taiwan Strait would constitute an act of aggression. Delivered by China’s Permanent Representative to the UN, Fu Cong, the letter also asserted China’s right to resolve such a scenario through resolute self-defense under international law.
This move comes amid mounting tensions after Japanese Prime Minister Sanae Takaichi publicly linked the possibility of deploying Japanese troops to a Taiwan Strait crisis, marking a significant shift from the traditionally ambiguous stance of prior Japanese leaders. Beijing strongly condemned these remarks, demanding a retraction—which Takaichi has so far refused—triggering a diplomatic and economic backlash from China.
In the letter, Fu Cong emphasized that Japan’s threat violates China’s sovereignty and territorial integrity, which Beijing considers a red line in its foreign relations. China also reminded the UN of Japan’s status as a defeated World War II aggressor, asserting that international legal frameworks—including “enemy State” clauses in the UN Charter—justify China’s potential countermeasures if Japan crosses this line.

The letter is being circulated to all UN member states with the intent to garner international awareness and pressure against Japan’s evolving defense posture. Experts interpret this as Beijing’s bid to rally global support while warning Tokyo against actions that may undermine regional peace and security, especially as Japan tests constitutional limits on collective self-defense.
With diplomatic relations between the two countries severely strained, the dispute highlights broader regional security challenges involving Taiwan’s contested status, the US’s strategic ambiguity, and shifting power dynamics in East Asia. The world closely watches as these developments unfold at the UN and beyond, with considerable implications for global stability.
