US Senate Majority Leader Chuck Schumer and his delegation met with Foreign Minister Wang Yi in Beijing on Monday, agency pool video showed.

Wang greeted Schumer and his delegation at the Diaoyutai State Guesthouse before going into a meeting, where Schumer thanked Wang for "welcoming us".

Schumer is the latest high-level US official to visit China as Washington seeks to ease tensions with Beijing.

On Saturday, he met with Chen Jining, the ruling Chinese Communist Party's chief official in Shanghai, according to a pool report, stressing the United States "does not want to decouple our economies".

In Shanghai, he also raised the issue of Chinese firms' role in the fentanyl drug addiction crisis in the United States.

"This is not the government but this is Chinese companies," he stressed.

"They are fuelling the fentanyl crisis that is poisoning communities across the United States," he said.

Bloomberg has reported his delegation is seeking a meeting with President Xi Jinping. (AFP)
