The measures, which come amid cratering relations between Beijing and Washington, are the latest in a promised series of steps intended to punish the U.S. for allowing the visit to the island it claims as its own territory, to be annexed by force if necessary. China on Thursday launched threatening military exercises in six zones just off Taiwan's coasts that it says will run through Sunday.
Missiles have also been fired over Taiwan, defense officials told state media. China routinely opposes the self-governing island having its own contacts with foreign governments, but its response to the Pelosi visit has been unusually vociferous.
The Foreign Ministry said dialogue between U.S. and Chinese regional commanders and defense department heads would be canceled, along with talks on military maritime safety.
Cooperation on returning illegal immigrants, criminal investigations, transnational crime, illegal drugs and climate change will be suspended, the ministry said.
The actions were taken because Pelosi visited Taiwan “in disregard of China’s strong opposition and serious representations," the ministry said in a statement.
China has accused the Biden administration of an attack on Chinese sovereignty, although Pelosi is head of the legislative branch of government and Biden had no authority to prevent her visit.
