China said on Friday it was conducting military exercises near the Taiwan Strait, as a top US diplomat visits the self-ruled island in a move that has angered Beijing.
Relations between the United States and China are at their lowest point in decades, with the two sides clashing over a range of trade, military and security issues as well as the coronavirus pandemic.
Keith Krach, US undersecretary of state for economic growth, energy and the environment, landed in Taipei on Thursday for a three-day visit, the highest-ranking State Department official to visit in 40 years.
At a press conference on Friday, a Chinese defence ministry spokesman said Beijing was “holding actual combat exercises near the Taiwan Strait” when asked how it would respond to the visit.
“This is a legitimate and necessary action taken to safeguard China’s sovereignty and territorial integrity in response to the current situation in the Taiwan Strait,” Ren Guoqiang told reporters.
Ren also warned that the Chinese military had “sufficient ability” to counter any external threat or challenge from Taiwan separatists.
Beijing considers Taiwan part of its territory, to be absorbed into the Chinese mainland – by force if necessary.
China’s Communist leadership baulks at any recognition of Taiwan – which has been ruled separately from China since the end of a civil war in 1949 – and has pursued a decades-long policy of marginalising the democratic island.
Ren accused the United States of “frequently causing trouble” over Taiwan, which he said “is purely China’s internal affairs, and we won’t tolerate any external interference”.
According to Taipei’s defence ministry, 18 Chinese aircraft – including bombers and fighters – entered Taiwan’s southwest air defence identification zone (ADIZ) on Friday and also crossed the so-called median line that divides the Taiwan Strait.
The ministry said Taiwan’s military “scrambled fighters, and deployed air defence missile system to monitor the activities”.
In recent weeks, Taiwan has reported a sharp rise in incursions by Chinese warplanes into its ADIZ.
Chinese jets also made a brief incursion across the midline of the strait separating the two sides in August, as US health chief Alex Azar made his country’s highest-level visit to Taiwan since 1979 – the year Washington switched diplomatic recognition to Beijing.
Washington’s increased outreach to Taiwan under President Donald Trump has become yet another US-China flashpoint.
The US said Krach was visiting Taiwan to attend a memorial service for late president Lee Teng-hui. He will also meet with foreign minister Joseph Wu, and is scheduled to join President Tsai Ing-wen for dinner at her official residence on Friday.
China has ramped up pressure on Taiwan since Tsai came to power in 2016, as she refuses to acknowledge its idea that the democratic island is part of “one China”.
