Taiwan needs to be on alert for China's "over the top" military activities, the premier said on Tuesday, after a record 56 Chinese aircraft flew into Taiwan's air defense zone, while the president said the island would do what it took to defend itself.

Taiwan has reported 148 Chinese air force planes in the southern and southwestern part of its air defense zone over a four day period beginning on Friday, the same day China marked a key patriotic holiday, National Day.

China claims Taiwan as its own territory, which should be taken by force if necessary. Taiwan says it is are an independent country and will defend their freedoms and democracy.
