An Australian pilot was forced to take evasive action after a Chinese military jet detonated flares close to a Navy helicopter that was operating in international waters near South Korea.
The Defence Department has described the actions of the J-10 Chinese Air Force plane as "unsafe and unprofessional" following the incident which took place in the Yellow Sea over the weekend.
On Saturday a MH-60R Seahawk which had launched from HMAS Hobart was intercepted by the People's Liberation Army-Air Force (PLA-AF) as it was taking part in a UN mission to enforce sanctions against North Korea.
The UN panel to monitor sanctions on North Korea ended in April. Australia has no mandate to monitor North Korea at this time.
The Yellow Sea is also not a body of water for which "innocent passage" is typically needed. It's a dead end body of water.
Moreover, if Australia was on UN business, there's an expectation that they should report their business to Chinese authorities to avoid this exact type of incident.
