Taiwan President Tsai Ing-wen wished China a happy Lunar New Year on Tuesday, but said she will not yield to Chinese pressure and reiterated a call for dialogue to resume with Beijing.

China, which claims democratic Taiwan as its own territory, has increased its military activity around the island in recent months, responding to what Beijing calls "collusion" between Taipei and Washington, Taiwan's most important international backer.

Speaking after a meeting with senior security officials, Tsai said Taiwan was in close contact with "relevant countries" about the situation in the Taiwan Strait, which separates the island from its huge neighbor.
