U.S. Speaker Pelosi Arrives In Taiwan Despite Warnings From China

House Speaker Nancy Pelosi has landed in Taiwan despite threats from Chinese officials of "resolute and strong measures" in response.

U.S. House Speaker Nancy Pelosi arrived in Taiwan on Tuesday night, becoming the highest-ranking American official to visit the self-ruled island that is claimed by China in 25 years.

Pelosi's visit has triggered increased tensions between China and the United States. China claims Taiwan as part of its territory, to be annexed by force if necessary, and views visits by foreign government officials as recognition of the island's sovereignty.
