China-Taiwan tensions

China on Wednesday repeated military threats against Taiwan while appearing to wind down wargames near the self-governing island it claims as its own territory that have raised tensions between the two sides to their highest level in years.

The message in a lengthy policy statement issued by the Cabinet’s Taiwan Affairs Office and its news department followed almost a week of missile firings and incursions into Taiwanese waters and airspace by Chinese warships and air force planes.

The actions disrupted flights and shipping in a region crucial to global supply chains, prompting strong condemnation from the U.S., Japan and others.

An English-language version of the Chinese statement said Beijing would “work with the greatest sincerity and exert our utmost efforts to achieve peaceful reunification.”

“But we will not renounce the use of force, and we reserve the option of taking all necessary measures. This is to guard against external interference and all separatist activities,” it said.

“We will always be ready to respond with the use of force or other necessary means to interference by external forces or radical action by separatist elements. Our ultimate goal is to ensure the prospects of China’s peaceful reunification and advance this process,” it said.

China says its threatening moves were prompted by a visit to Taiwan last week by U.S. House Speaker Nancy Pelosi, but Taiwan says such visits are routine and that China used her trip merely as a pretext to up its threats.

In an additional response to Pelosi’s visit, China said it was cutting off dialogue on issues from maritime security to climate change with the U.S., Taiwan’s chief military and political backer.

Taiwan’s foreign minister warned Tuesday that the Chinese military drills reflect ambitions to control large swaths of the western Pacific, while Taipei conducted its own exercises to underscore its readiness to defend itself.

Beijing’s strategy would include controlling the East and South China seas via the Taiwan Strait and imposing a blockade to prevent the U.S. and its allies from aiding Taiwan in the event of an attack, Joseph Wu told a news conference in Taipei.

Beijing extended the ongoing exercises without announcing when they would end, although they appeared to have run their course for the time being.

In London, the British government summoned Chinese Ambassador Zheng Zeguang to the Foreign Office on Wednesday to demand an explanation of ”Beijing’s aggressive and wide-ranging escalation against Taiwan” following Pelosi’s visit.

“We have seen increasingly aggressive behavior and rhetoric from Beijing in recent months, which threaten peace and stability in the region,” said Foreign Secretary Liz Truss. “The United Kingdom urges China to resolve any differences by peaceful means, without the threat or use of force or coercion.”
