Taiwan reported on Thursday a second day of large-scale Chinese air force incursions into its air defense identification zone, with its defense ministry saying that over 24 hours it had spotted 21 aircraft, amid Beijing's military pressure campaign.
Taiwan, which China views as its own territory, has complained for the past three years or so of stepped-up Chinese military activities near the island as Beijing seeks to assert its sovereignty claims.
China has said its activities in the area are justified as it seeks to defend its territorial integrity and to warn the United States against "colluding" with Taiwan, despite the anger this causes in Taipei.
