The U.S. military accused China of performing “an unnecessarily aggressive maneuver” over the South China Sea last week when a People’s Liberation Army fighter jet intercepted a U.S. reconnaissance plane.

The Pentagon also posted a 26-second video of the incident, from the U.S. aircraft’s interior, showing the Chinese jet streak in front of the American plane’s flight path.

“The PRC pilot flew directly in front of the nose of the RC-135, forcing the U.S. aircraft to fly through its wake turbulence. The RC-135 was conducting safe and routine operations over the South China Sea in international airspace, in accordance with international law,” said U.S. Indo-Pacific Command, in a statement disclosing that the incident had taken place on May 26.

The PLA carried out a similarly provocative maneuver last December, when a Chinese fighter jet flew within 20 feet of a U.S. RC-135. After that incident, Indo-Pacific Command also published a video of the intercept by the Chinese jet.

And as recently as last week, just a few days before this month’s intercept, Admiral John Aquilino, the U.S. Indo-Pacific Commander, said that he was concerned about “an increasing number of dangerous and escalatory actions against the U.S. and our allies and partners that, No. 1, increase our concern for potential accidents and miscalculation, but [No.] 2 are in opposition to the international rules of order and safety.”

Aquilino added that “we’ve seen the intercepts of our aircraft become much closer and ultimately more dangerous,” specifically mentioning the intercept in December.

As the occurrence of PLA provocations has increased, top Chinese officials have stonewalled U.S. requests for dialogue, even as Chinese government and Chinese Communist Party leaders have started to engage their U.S. counterparts on trade issues.

Aquilino also said last week, during the same appearance, at an event hosted by the National Committee on U.S.-China Relations, that his Chinese military counterparts have rejected all of his requests to hold talks about minimizing the risk posed by potential accidents.

“I do not believe that engaging in an open and candid discussion should be used as a bargaining chip,” he said.

And on Monday, the Wall Street Journal reported that Chinese defense minister Li Shangfu had officially turned down Defense secretary Lloyd Austin’s request for a meeting on the sidelines of the Shangri La Dialogue this week, with Chinese officials using “unusually blunt language.” Chinese officials had implied that lifting U.S. sanctions placed on Li in 2018 for his role in acquiring Russian weapons for China was a prerequisite for the meeting.

Interestingly, some Chinese diplomats seem to understand that Beijing’s continued stonewalling of security talks are liable to making China look unreasonable. During Aquilino’s speech last week, a Chinese military attache posted to the country’s U.N. mission spoke up to claim that China is committed to “peaceful coexistence.”

The U.S. commander responded to the unexpected comment by the Chinese official saying that he is eager to see that demonstrated in practice, starting with the conversations he requested with Chinese commanders.
