Officials in Taiwan say that 39 Chinese military aircraft and three vessels entered an area close to the island on Thursday morning local time.

"And we are quite sure that the Chinese may want to use another pretext of practicing their future attacks against Taiwan. So this is a military threat against Taiwan," Wu told The Guardian.
