(Bloomberg) -- China called on US House Speaker Kevin McCarthy not to visit Taiwan, raising the specter of a repeat of the showdown last year when his predecessor, Nancy Pelosi, made her own trip to the democratically run island.

“We urge certain individuals in the US to earnestly abide by the one-China principle,” Foreign Ministry spokeswoman Mao Ning told a regular news briefing Monday, referring to Beijing’s belief that both sides are part of the same country. They should also “stop doing anything that violates the basic norms in international relations,” Mao said. 

Although Mao stopped short of using McCarthy’s name, she was responding to a question about a report last week that the California Republican was planning to visit Taiwan. She didn’t say what China would do in response to any such trip. 

The People’s Liberation Army held unprecedented drills around the island and fired missiles over Taipei in August, when Pelosi, a Democrat, became the first House speaker in 25 years to visit Taiwan. McCarthy had at the time pledged to make his own trip to the island should his party win the House in the mid-terms. 

While relations between the US and China have improved since President Joe Biden held his first face-to-face meeting with counterpart Xi Jinping in November, Beijing has repeatedly indicated that it has no room to compromise on Taiwan’s sovereignty. Washington cut formal ties with Taipei more than four decades ago, as part of a deal to normalize relations with Beijing, which claims Taiwan as its territory. 

Meanwhile, Mao sidestepped a question about an internal memo by a US Air Force general warning about the need to prepare for war with China in 2025. General Mike Minihan, head of the Air Force’s Air Mobility Command, said in an internal memo that he had a gut feeling that conflict over Taiwan would happen in two years, NBC reported Friday.

Mao reaffirmed that China would “never promise to give up the use of force” to unify the two sides, but said Beijing hoped hoped to resolve disputes over the island peacefully.
