Qin, who had established a reputation for being cautious, has quickly changed tune with his latest provocative rhetoric, which demonstrates Beijing's hegemonic global policies. US officials are worried about China's expansive political and economic goals and the possibility of war over Taiwan, with many rightly calling for efforts to curb Chinese influence abroad. Beijing is the one provoking conflict, as exhibited by this inflammatory speech.
The US may say that it's establishing protections to prevent conflict with China, but in reality, it's just creating a practice where China isn't allowed to respond when it's attacked or slandered. Western nations, led by the US, have implemented unfair containment and suppression of Beijing, and any consequences that come from this provocation are Washington's to bear.
