BEIJING/TAIPEI: The Chinese military on Sunday condemned the United States and Canada for each sending a warship through the Taiwan Strait last week, saying they were threatening peace and stability in the region.

The US military said the Arleigh Burke-class guided missile destroyer USS Dewey sailed through the narrow waterway that separates Taiwan from its giant neighbour China along with the Canadian frigate HMCS Winnipeg on Thursday and Friday.

"Dewey's and Winnipeg's transit through the Taiwan Strait demonstrates the commitment of the United States and our allies and partners to a free and open Indo-Pacific," it added.

China's People's Liberation Army's Eastern Theatre Command said its forces monitored the ships and "stood guard" throughout their passage.

"The United States and Canada colluded to provoke and stir up trouble... seriously jeopardising peace and stability of the Taiwan Strait," it said.

"Taiwan is part of Chinese territory. Theatre forces always maintain a high level of alert and resolutely counter all threats and provocations." U.S. Navy ships have been transiting the strait roughly monthly, to the anger of Beijing, which has accused Washington of stoking regional tensions. US allies occasionally also send ships through the strait, including Britain.
