United States does not seek to change the status quo in the Taiwan Strait, US House of Representatives Speaker Nancy Pelosi said on Friday in Japan.

"We said from the start that our representation here is not about changing the status quo here in Asia and the status quo in Taiwan," Pelosi said during a press conference at the US embassy in Tokyo, the last stop on her Asia tour that has also taken her to Singapore, Malaysia and South Korea, democracies that she sought to "celebrate" with the trip.

"It's a ridiculous question," Pelosi said when asked about speculation that her visit to Taipei was more about boosting her own legacy than to benefit Taiwan.

Infuriated with the visit, China has retaliated against Taiwan with live-fire drills and missile launches around the island, as well as economic measures.
