US House Speaker Nancy Pelosi landed in Taipei on Tuesday, a stop on her tour through Asia and a significant show of diplomatic support for Taiwan despite China's threats of retaliation.

Taiwan has emerged as a serious point of conflict between the US and China, as US officials fear a more imminent Chinese move on the self-governing island. The visit prompted warnings from China as well as the Biden administration, which has briefed the speaker about the risks of visiting the democratic, self-governing island that China claims as part of its territory.

Throughout her career in Congress, Pelosi has a long history of representing the US to Chinese officials, including standing up to Beijing as well as presidents from her own party.

Pelosi, speaking at the US Capitol in June 1991, holds a watch that was reportedly smuggled out of China. She said the watches were given to soldiers who helped crush the Tiananmen Square protesters in 1989.
