China accused an Australian military aircraft of conducting dangerous maneuvers, escalating a dispute over a recent incident involving the nations' two militaries.

"What truly happened was an Australian military aircraft deliberately flew within close range of China's airspace in a provocative move that endangered China's maritime air security in the name of enforcing a UN Security Council resolution," Foreign Ministry spokesman Lin Jian said at a regular press briefing on Tuesday.

Australia's Defence Department said earlier that a People's Liberation Army aircraft intercepted one of its helicopters in the Yellow Sea on May 4 and "released flares along the flight path." But Lin said the Chinese aircraft took "necessary measures" to alert the Australian chopper. He added that Beijing lodged a "serious protest" with Australia.

China's Defense Ministry also said in a statement on Tuesday its actions were reasonable and safe, and accused the Australian helicopter of conducting reconnaissance of military training.

China's response comes after Prime Minister Anthony Albanese said Australia had expressed its concern to Beijing through diplomatic channels, describing the incident as both "unprofessional" and "unacceptable."

Albanese said Australian defense personnel shouldn't be at risk when they're "going about their job." The helicopter was operating from an Australian naval vessel enforcing United Nations sanctions against North Korea, Australia's Department of Defence said in a statement.

The incident came after Australia's chief of navy, Vice Admiral Mark Hammond, met with the head of China's navy, Admiral Hu Zhongming, at a naval symposium last month in Qingdao.

Hammond stressed the importance of "safe and professional behavior" between the two navies, according to Australia's Department of Defence. He mentioned an incident in November where two Australian navy divers were injured by sonar pulses from a Chinese naval vessel.

The Chinese reaction on Tuesday was similar to how Beijing responded to the earlier incident. Back then, China told Australia to "stop making trouble in front of China's doorsteps and work with China to preserve the momentum of improving and growing China-Australia ties."

It followed up by calling the Australian comments "irresponsible accusations."
