China’s military announced Wednesday that its fighter jets shadowed a U.S. Navy aircraft that flew over the Taiwan Strait.
The People's Liberation Army said it deployed fighters to warn the P-8A Poseidon maritime patrol aircraft and "deal with it in accordance with the law and regulations," according to Reuters.
"Troops in the theatre are always on high alert and will resolutely defend national sovereignty and security as well as regional peace and stability," the news agency quoted its Eastern Theatre Command as saying.
China has long claimed to hold sovereignty over the Taiwan Strait and the island itself, something not recognized by the U.S. or international law.
US NAVY RESPONDS AFTER CHINA CLAIMS AMERICAN WARSHIP ‘ILLEGALLY INTRUDED’ INTO THE SOUTH CHINA SEA
The U.S. 7th Fleet Public Affairs Office said the Navy P-8A Poseidon "transited the Taiwan Strait in international airspace on Dec. 6.
"By operating within the Taiwan Strait in accordance with international law, the United States upholds the navigational rights and freedoms of all nations. The aircraft's transit of the Taiwan Strait demonstrates the United States' commitment to a free and open Indo-Pacific," it said. "The United States military flies, sails and operates anywhere international law allows."
Taiwan’s defense ministry said its troops monitored the aircraft as it flew south, describing the situation as "normal," Reuters reports.
China offered a similar rebuke when another Navy P-8A Poseidon flew through the Taiwan Strait on Oct. 12.
