Just 12 days after US House Speaker Nancy Pelosi visited the island of Taiwan, a delegation of US lawmakers made a sudden visit to the island on Sunday, further proving that the US is the one that makes repeated provocations and keeps tensions from easing, said Chinese experts.

They stressed that China will definitely impose sanctions on the visiting lawmakers as a countermeasure, as the country has always been firmly opposed to any collusion between the US and Taiwan secessionists.
