Beijing, which claims democratically governed Taiwan as its own territory, has conducted military drills around the island after U.S. House of Representatives Speaker Nancy Pelosi's visit to Taipei in early August.

China has long claimed sovereignty over the island. Taiwan's government rejects China's claims and says the island's people should decide its future.

The de facto U.S. embassy in Taipei said the delegation is being led by Senator Ed Markey, who is being accompanied by four House lawmakers on what it described as part of a larger visit to the Indo-Pacific region.

Taiwan's presidential office said the group would meet Tsai on Monday morning.

"Especially at a time when China is raising tensions in the Taiwan Strait and the region with military exercises, Markey leading a delegation to visit Taiwan once again demonstrates the United States Congress' firm support for Taiwan," it said in a statement.

Markey chairs the Senate Foreign Relations East Asia, Pacific, and International Cybersecurity Subcommittee.

The co-leaders of the visit are Representative John Garamendi of the congressional Nuclear Weapons and Arms Control Working Group and Representative Don Beyer, a spokesperson for Markey said.

China's embassy in Washington said on Sunday that "Members of the U.S. Congress should act in consistence with the U.S. government's one-China policy" and argued the latest congressional visit "Once again proves that the U.S. does not want to see stability across the Taiwan Straits and has spared no effort to stir up confrontation between the two sides and interfere in China's internal affairs."

A spokesperson for the White House National Security Council said members of Congress have gone to Taiwan for decades and will continue to do so, adding that such visits were in accordance with the United States' long-standing one-China policy.

Markey's office said the lawmakers in Taiwan "will reaffirm the United States' support for Taiwan as guided by the Taiwan Relations Act, U.S.-China Joint Communiques, and Six Assurances, and will encourage stability and peace across the Taiwan Strait."

Shared Interests:

The group will meet "with elected leaders and members of the private sector to discuss shared interests including reducing tensions in the Taiwan Strait and expanding economic cooperation, including investments in semiconductors," Markey's office said.

"The delegation will meet with senior Taiwan leaders to discuss U.S.-Taiwan relations, regional security, trade and investment, global supply chains, climate change, and other significant issues of mutual interest," the de facto U.S embassy said
