Taipei, Taiwan (CNN)-- Twenty-eight Chinese military planes flew into Taiwan's Air Defense Identification Zones (ADIZ) Tuesday -- the largest incursion since the self-ruled island began regularly reporting such actions last year, according to Taiwan's Ministry of Defense.
Tuesday's flights -- which included fighter jets, bombers, and anti-submarine and early warning aircraft -- surpassed the previous peak of 25 planes reported April 12.
Beijing claims full sovereignty over Taiwan, a democracy of almost 24 million people located off the southeastern coast of mainland China, even though the two sides have been governed separately for more than seven decades.
