China's Foreign Ministry has scolded Peter Dutton after he described the presence of a Chinese surveillance ship off the coast of Western Australia as an "act of aggression".
Foreign Ministry spokesperson Zhao Lijian was quizzed about the remarks at a press conference overnight.
"I would like to state that China always follows international law and common practice," Zhao said.

"The Australian politician concerned should view the situation with objectivity and calm, instead of making sensational comments aimed at fear-mongering."

"It is strange timing and without precedent."
He described it as an "act of aggression".
But earlier today Prime Minister Scott Morrison struck a more moderate tone.

Haiwangxing entered Australia's Exclusive Economic Zone on the morning of May 6.

It turned north, and by May 11 it was 50 nautical miles from HEHCS. It then steamed north and by May 13 had been tracked off the port of Broome, thought to be heading towards Darwin.
