A Chinese fighter aircraft dangerously intercepted an Australian military surveillance plane in the South China Sea region in May, Australia's defence department said on Sunday, Trend reports citing Reuters.
The Royal Australian Air Force P-8 maritime surveillance aircraft was intercepted by a Chinese J-16 fighter during "routine maritime surveillance activity" in international airspace in the region on May 26, defence said in a statement.
"The intercept resulted in a dangerous manoeuvre which posed a safety threat to the P-8 aircraft and its crew," it said.
Prime Minister Anthony Albanese told reporters in Perth that his government had expressed concerns to China "through appropriate channels".
China's embassy in Australia did not immediately respond to a request for comment.
Defence Minister Richard Marles said the Chinese jet flew very close in front of the RAAF aircraft and released a "bundle of chaff" containing small pieces of aluminium that were ingested into the Australian aircraft's engine.
"Quite obviously this is very dangerous," Marles told ABC television.
Australia has previously joined the United States in stating that China’s claims around contested islands in the South China Sea do not comply with international law.
Defence said for decades it had undertaken maritime surveillance in the region and "does so in accordance with international law, exercising the right to freedom of navigation and overflight in international waters and airspace".
