he Chinese military cried foul on Wednesday after U.S. Navy warship the USS John Finn sailed through the sensitive waters of the Taiwan Strait for the first time this year.

The Eastern Theater Command of the Chinese People’s Liberation Army said the United States “openly hyped up” the move by publicizing its transit through the 100-mile-wide strait, according to spokesperson Col. Shi Yi, who said the U.S. had “frequently carried out provocative acts and maliciously undermined regional peace and stability.”

The calculated display of U.S. military presence comes amid ongoing cross-strait tensions between Beijing and Taipei, which American and Taiwanese analysts fear could reach a crisis point this year.
