Japan’s Defence Minister Shinjiro Koizumi accused China’s J-15 fighter jets of aiming fire control radar at Japanese aircraft during two separate incidents over international waters near Okinawa.

A fire-control radar lock is one of the most threatening acts a military aircraft can take, Tokyo lodged a strong protest, calling the radar lock a dangerous act that signals a possible attack and forces evasive action.

China denied the claim, saying Japan’s aircraft disrupted its navy during training.

The encounters are the most serious in years and come amid rising tensions over Taiwan. No damage or injuries were reported.
