China has brought its escalating dispute with Japan over Taiwan to the United Nations, accusing Tokyo of threatening armed intervention. In a letter to UN Secretary-General Antonio Guterres, China's UN Ambassador Fu Cong condemned Japanese Prime Minister Sanae Takaichi's remarks, which suggested that a Chinese attack on Taiwan could prompt a military response from Japan. Fu stated that any armed intervention by Japan would be considered an act of aggression and emphasized China's right to self-defense under international law. This dispute has intensified tensions between the two countries, impacting trade and cultural exchanges. Japan's Prime Minister has shifted from a previously ambiguous stance on Taiwan, indicating that a Chinese attack could threaten Japan's survival. The situation reflects broader geopolitical tensions in the region, particularly concerning Taiwan's status and China's claims over the island.
