22-11-2025 (BEIJING) Beijing formally elevated its intensifying diplomatic dispute with Tokyo over Taiwan to the United Nations, asserting it would “resolutely exercise its right of self-defence” if Japan attempts any armed intervention in the cross-Strait situation, as reported by multiple international news outlets. China’s Permanent Representative to the UN, Fu Cong, delivered a letter to Secretary-General Antonio Guterres on Friday, marking a significant international escalation of the bilateral crisis.

The letter condemned recent statements by Japanese Prime Minister Sanae Takaichi, accusing her of committing a “grave violation of international law” and diplomatic norms. The controversy stems from Takaichi’s suggestion earlier this month that a hypothetical Chinese attack on Taiwan could be deemed a “situation threatening Japan’s survival,” a legal designation that permits the deployment of Japan’s military. Beijing, which views the self-governed island as its own territory, stated that such an act would constitute an “act of aggression.”

This diplomatic move follows escalating bilateral rhetoric and China’s reported suspension of Japanese seafood imports, underscoring the severity of the largest crisis between the two major Asian powers in years. Global leaders and regional defense analysts will now closely watch for any official rebuttal from Japan at the UN and any immediate steps taken by either nation to de-escalate tensions.
