Joseph Wu, secretary-general of Taiwan’s National Security Council, said in a post on X that the deployment had taken place over the past few days following U.S. President Donald Trump’s meeting with Chinese President Xi Jinping in Beijing. Wu said China was undermining the status quo and threatening peace and stability in the region.

A Taiwan security official, speaking on condition of anonymity, told AFP that Chinese vessels had been detected before the Beijing summit but that the number operating in the region had risen above 100 in recent days.

China, which views democratically governed Taiwan as part of its territory, has repeatedly stated that it reserves the right to use force to bring the island under its control.

Taiwan rejects Beijing’s sovereignty claims and maintains that only its people can determine the island’s future.The reported increase in Chinese maritime activity came days after Trump referred to “the Taiwan problem” when asked whether he would discuss arms sales with Taiwanese President Lai Ching-te.

Trump said he would speak with Lai and noted that he had held what he described as a productive meeting with Xi during his state visit to China.“We’ll work on that, the Taiwan problem,” Trump said on Wednesday.

Taiwan has frequently reported heightened Chinese military and coast guard operations around the island, activities that Taipei says are aimed at increasing pressure on its government and testing regional security responses.

The latest deployment, according to Taiwanese officials, extended across multiple strategic waterways in East Asia, underscoring Beijing’s expanding maritime presence at a time of heightened geopolitical scrutiny in the Taiwan Strait and surrounding seas.
