A rise in “dangerous maneuvers” by China’s military risks “a crisis or conflict” in the South China Sea or Taiwan Strait, the U.S. assistant secretary of defense responsible for the region said Thursday.
The Pentagon has in the past two weeks released footage of two incidents of near-accidents involving Chinese vessels. 
The first, from May 26, shows a Chinese jet veering suddenly in front of a U.S. reconnaissance plane over the South China Sea. The second, from June 2, shows a similar maneuver from a Chinese warship.
It’s part of a “steep rise” in “aggressive, unprofessional, risky, unsafe behavior” that has also included the release of flares and chaff – clusters of metal pieces – at U.S.-allied aircraft, said Ely Ratner, assistant secretary of defense for Indo-Pacific security affairs.

“It"s happening in the context of [China’s military] being unwilling to engage with the United States in military-to-military communications – not just crisis communications, but dialogue as well,” he said.
American defense officials have complained about their Chinese counterparts’ refusal to speak on the phone since U.S. Secretary of State Antony Blinken nixed a February trip to Beijing after an alleged Chinese spy balloon was discovered over the United States.
China’s new defense minister, Li Shangfu, also declined an invitation to meet with U.S. Defense Secretary Lloyd Austin when they were in Singapore last weekend for the annual Shangri-La Dialogue.
“We think that"s really problematic,” Ratner said.
Cold thaw 
Ratner’s comments come amid strained efforts by U.S. diplomats to re-engage with China after nearly a year of rising tensions that began with then-House Speaker Nancy Pelosi’s August visit to Taiwan.
The relationship has been further strained by the spy balloon, Blinken’s canceled Beijing trip, an unofficial visit to the United States by Taiwanese President Tsai Ing-wen and U.S. efforts to cut China’s technology sector off from high-end American microchips.
Meanwhile, there has also been no shortage of warnings from U.S. generals of an imminent invasion of Taiwan by China as early as later this year, and Republican and Democratic lawmakers have seized on China policy as a rare area of bipartisan unity.
However, two senior U.S. officials were in Beijing on Monday in an attempt to pave the way for a new Blinken visit to Beijing, and there have been reports the U.S. secretary of state will make the trip within weeks. President Joe Biden has also predicted a thaw.

Liu Pengyu, spokesperson for the Chinese Embassy in Washington, told Radio Free Asia last month that the “provocative and dangerous moves” by American military vessels in their “close-in reconnaissance on China” was the ultimate cause of the recent near-accidents.
Ratner told the CNAS conference any suggestion that the U.S. military was even partly to blame in the incidents “makes me want to tear my hair out” given the aggressive maneuvers from China.
“We"re going to continue to fly, sail and operate safely and responsibly, in accordance with international law, as we have been doing,” he said Thursday. “This is a major problem.”
