"Related remarks from the US side are inconsistent with fact," Wu Qian, a spokesman for the Defense Ministry, said on Sunday. "The Chinese aircraft investigated the US plane in accordance with the law, and related maneuvers were professional and safe."
"Recently, the US military has frequently dispatched planes and ships into China's waters and airspace, threatening our sovereignty and security, as well as putting the lives of front-line staff in danger," he added.
On May 25, two Chinese J-10 fighter jets came within 182 meters of a P-3 Orion surveillance plane flying 240 kilometers southeast of Hong Kong.
On the same day, the USS Dewey, a US guided missile destroyer, was sailing near some of the Nansha Islands in the South China Sea. The People's Liberation Army Navy dispatched two frigates to investigate and warn the US ship to leave.
On May 17, a US WC-135 Constant Phoenix reconnaissance aircraft was carrying out operations in airspace over China's Yellow Sea, and Chinese aircraft acted to identify and investigate in accordance with the law, the statement said, calling the action "professional" and "safe", according to the ministry's previous statements.
"These actions are the root cause of the security issue between China and the US, both in the air and at sea," Wu said. "We again urge the US to take concrete actions to correct and avoid such incidents from happening again."
