These exercises is done by China to gauge their neighbours capabilities (see the entire Cold War dickswinging whenever there's an airspace intrusion).
ASDF knows better than to evade a radar lock during peace time. Make it into a diplomatic incident and having it locked on for 30 minutes is proof that PLAAF was doing it deliberately.
yup, and this incident has given another free bullet to Takaichi to strengthen the nationlism of Japanese, which further solidify her support ratings
