A US destroyer and a Canadian frigate sailed through the Taiwan Strait on Wednesday. The US and Canadian navies conducted a similar transit in September.
The US Navy's 7th Fleet said its guided-missile destroyer USS Rafael Peralta and Royal Canadian Navy frigate HMCS Ottawa conducted a "routine Taiwan Strait transit."
It said the ships sailed through "a corridor in the Strait that is beyond the territorial sea of any coastal State," and that the transit was "unremarkable, unprovocative, and consistent with international law."
The 7th Fleet also said the bilateral transit "demonstrates the commitment of the United States and our allies and partners to a free and open Indo-Pacific."
Taiwan's defense ministry says the two warships sailed north through the strait on Wednesday night.
HMCS Ottawa and the US guided-missile destroyer, USS Ralph Johnson, made a similar transit in September.
The Chinese military has recently been stepping up its activities around Taiwan. In late October, Chinese aircraft carrier Shandong sailed through the Bashi Channel between Taiwan and the Philippines and held drills in the Western Pacific.
