In Taiwan, anger has been growing over China’s refusal this week to let Taiwan evacuate about 300 of its people from Wuhan, even as it has given the United States, Japan and other countries permission to do so.

China’s ruling Communist Party considers Taiwan, a democratically governed island, to be part of China, and the two sides have no formal ties. Referring to the rebuffed evacuation request on Tuesday, Ma Xiaoguang, a spokesman for China’s Taiwan Affairs Office, said in a statement that Taiwanese people in Hubei Province, which includes Wuhan, were receiving “appropriate care.”

Kolas Yotaka, a spokeswoman for Taiwan’s government, said China was prioritizing politics over lives. Many of the Taiwanese seeking evacuation from Wuhan were tourists or on business trips, while others were residents of the city who suffered from chronic diseases, Ms. Kolas said.

“We call on the Chinese government to demonstrate basic humanity and agree to our request as soon as possible,” she said.

As part of its campaign to isolate Taiwan diplomatically, China has blocked it from participating in international bodies like the World Health Organization — a fact that has also angered Taiwanese people this week, as they try to prepare along with the rest of the world for the possibility of a worsening epidemic.
