Taipei: Taiwan said on Saturday that 47 Chinese aircraft and seven naval vessels, as well as one official ship, were detected operating around the island nation.

According to Anadolu Agency, Taiwan's Defense Ministry reported that 41 out of the People's Liberation Army aircraft crossed the median line and entered Taiwan's northern, southwestern, and eastern air defense identification zone.

The aircraft and vessels were detected until 6 a.m. local time (2200GMT). The ministry stated that they have monitored and employed aircraft, navy ships, and coastal missile systems in response to the detected activities.

An air defense identification zone is a designated area of international airspace extending beyond a nation's sovereign borders where aircraft identification is required for national security purposes. China, which considers Taiwan a breakaway province, does not recognize the median line or the air defense zone. Taipei, however, has insisted on its independence since 1949.
