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.
