Beijing is warning Australia will “bear the consequences” if there are any military disputes in the South China Sea

China’s Defence Ministry says Australia is engaging in “risky” behaviour, as surveillance jets fly near the disputed Paracel Islands.

“What is the duty of a soldier? That is to defend the homeland,” says Colonel Tan Kefei.

The islands are claimed by China, Vietnam and Taiwan.

It comes just weeks after an Australian Air Force was challenged by a Chinese J-16 fighter in the disputed territory.

Australia’s Defence Minister Richard Marles says some aluminium chaff was drawn into the engines of the P-8A Poseidon.

“The J-16 then accelerated and cut across the nose of the P-8 settling in front of the P-8 at a very close distance,” he said.

The aircraft made its way back to its base, and Marles said the crew responded “professionally”.

It’s believed the Chinese jet also fired flares and chaff as a countermeasure.

The Defence Minister said he had communicated his concerns to Chinese authorities over the incident.

But China’s defence spokesperson, Colonel Tan says “those who come uninvited shall bear the consequences.”

Canada has also been in the firing line, as they reportedly carry out U.N. missions near North Korea.

But Chinese authorities believe the jets were monitoring China “under the pretext of enforcing U.N. Security Council resolutions”.

“No matter what the name or excuse is, it is completely unreasonable to send military planes to the door of others to provoke and jeopardise the national security of other countries,” says Colonel Tan.

Australia’s Prime Minister met with Canada’s leader, Justin Trudeau on the sidelines of the NATO Summit in Madrid this week.
