"Speaker Nancy Pelosi is leading a Congressional delegation to the Indo-Pacific region, including visits to Singapore, Malaysia, South Korea and Japan," her office said in a press release.
The statement issued by the Cabinet’s Taiwan Affairs Office and its news department followed almost a week of missile firings and incursions into Taiwanese waters and airspace by Chinese warships and air force planes.
A person familiar with the matter confirmed that Pelosi and her delegation landed in the city-state before dawn. They spoke on condition of anonymity because they were not authorized to release details to the media.
Pelosi landed at a Malaysian air force base ahead of meetings with the prime minister and the speaker of the lower house of parliament, state news agency Bernama reported.
"Today the world faces a choice between democracy and autocracy,” she said in a short speech during a meeting with President Tsai Ing-wen. "America’s determination to preserve democracy, here in Taiwan and around the world, remains ironclad.”
China's Customs Administration said it would suspend some citrus fruits and fish imports from Taiwan over alleged "repeated" detection of excessive pesticide residue and positive coronavirus tests on packages; bans shipments of sand to the island.
The White House summoned China's ambassador, Qin Gang, late on Thursday to tell him that the military actions were of "concern to Taiwan, to us and to our partners around the world," said spokesman John Kirby.
The official Xinhua News Agency said on Friday that fighters, bombers, destroyers and frigates were all used in what it called "joint blockage operations” taking place in six zones off the coast of Taiwan, which China claims as its own territory.
On Saturday, Jo Yong Sam, director general at the North Korean Foreign Ministry's press and information affairs department, slammed Pelosi over her visit to the border and discussion of anti-North Korean deterrence.
Paul Pelosi, 82, was booked into the Napa County Detention Center after being charged with two misdemeanors and bail was set at $5,000, according to police and county online records. On Sunday, he was not listed as being in custody.
