Ten Chinese warplanes entered Taiwan's air defense identification zone on Friday, the self-governed island's Defense Ministry said, as its military concluded an annual large-scale drill.

A total of 25 Chinese warplanes have entered the zone during the Han Kuang Exercise since its start on Monday, according to the ministry. Some of the 10 planes crossed the Bashi Channel, separating southern Taiwan from the Philippines, and flew over waters off the island's eastern shore.

Beijing, which considers Taiwan a renegade province to be reunified, has been stepping up military pressure on the island.
