Two U.S. Navy ships sailed through the sensitive Taiwan Strait this week in the first such mission since President Donald Trump took office last month, drawing an angry reaction from China, which said the mission increased security risks.
The U.S. Navy, occasionally accompanied by ships from allied countries, transits the strait about once a month. China, which claims Taiwan as its own territory, says the strategic waterway belongs to it.
The U.S. Navy said the vessels were the Arleigh Burke-class guided-missile destroyer USS Ralph Johnson and Pathfinder-class survey ship, USNS Bowditch. The ships carried out a north-to-south transit Feb. 10-12, it said.
"The transit occurred through a corridor in the Taiwan Strait that is beyond any coastal state's territorial seas," said Navy Cmdr. Matthew Comer, a spokesperson at the U.S. military's Indo-Pacific Command. "Within this corridor all nations enjoy high-seas freedom of navigation, overflight, and other internationally lawful uses of the sea related to these freedoms."
China's military said that Chinese forces had been dispatched to keep watch.
"The U.S. action sends the wrong signals and increases security risks," the Eastern Theater Command of the People's Liberation Army said in a statement early Wednesday.
Taiwan's defense ministry said its forces had also kept watch but noted the "situation was as normal."
The last publicly acknowledged U.S. Navy mission in the strait was in late November, when a P-8A Poseidon maritime patrol aircraft flew over the waterway.
The last time a U.S. Navy ship was confirmed to have sailed through the strait was in October, a joint mission with a Canadian warship.
China's military operates daily in the strait as part of what Taiwan's government views as part of Beijing's pressure campaign.
On Wednesday, Taiwan's defense ministry said that it had detected 30 Chinese military aircraft and seven navy ships operating around the island
