Chinese military rehearse encirclement of Taiwan

China's military has begun rehearsing the encirclement of Taiwan during three days of military drills. Beijing - which views Taiwan as a breakaway province of China - called the operation a "stern warning" to the island's government. The exercises began hours after President Tsai Ing-wen returned from a trip to the United States. The Taiwanese Defence Ministry said 42 Chinese military planes and eight ships crossed the Taiwan Strait median line.
