The Ministry of Foreign Affairs responded that Chinese military aircraft carried out "unnecessary aggressive maneuvers" in the South China Sea. The US Indian Ocean-Pacific Command issued a statement on Tuesday local time, saying that a Chinese Air Force J-16 fighter plane recently carried out "unnecessary aggressive maneuvers" in front of the US RC-135 strategic reconnaissance plane over the South China Sea. In response to relevant inquiries at a regular press conference on May 31, Foreign Ministry spokesman Mao Ning said: I would like to point out that the US side has long and frequently sent warships and aircraft to conduct approach reconnaissance on China, seriously endangering China's national sovereignty and security. Such provocative and dangerous actions are the root cause of maritime security problems, and the US side should immediately stop such dangerous provocative actions. Mao Ning said that China will continue to take necessary measures to firmly safeguard its own sovereignty and security.
