The actions of the United States and Canada disrupted the peace and stability of the Taiwan Straits, a military spokesperson said on Monday in response to U.S. and Canadian warships sailing through the straits on Sunday.

The Eastern Theater Command of the Chinese People's Liberation Army remains on high alert at all times and resolutely safeguards national sovereignty and security, as well as regional peace and stability, said Li Xi, a spokesperson for the command.

On Sunday, the U.S. destroyer Higgins and the Canadian frigate Vancouver transited through the straits, the spokesperson said.

Naval and air forces organized by the command closely followed and monitored the vessels' passage through the straits during the entire process and addressed the situation in accordance with laws and regulations, Li said.
