On Wednesday, a Chinese envoy warned that any Japanese military intervention in the Taiwan question would be met with a resolute response from China.

Fu Cong, China's permanent representative to the United Nations, said recent remarks by the Japanese leader linking Taiwan to Japan's "survival crisis" and suggested responses based on the U.S.-Japan alliance run counter to historical trends.

China would strike back forcefully if Japan, under any pretext, exercised so-called "collective self-defense" or intervened in the Taiwan question, he warned.
