Taiwan’s air force scrambled on Sunday to intercept Chinese jets that flew around the island claimed by Beijing as its own, in a move denounced by Taiwan’s Defence Ministry as a threat to regional peace and stability. China has been flying what it calls “island encirclement” drills on-off since 2016 when Taiwan President Tsai Ing-wen first took office. Beijing believes Tsai, who won re-election last month, wishes to push the island’s formal independence.
