Taiwan President's U.S. Visit Sparks Tensions with China.

Taiwan's President Tsai Ing-wen's visit to the US has sparked tensions with China, which considers Taiwan a breakaway province. The visit comes at a time when US-China relations are already strained due to trade disputes and the coronavirus pandemic. The US has maintained unofficial relations with Taiwan since 1979, but China has repeatedly warned against any official contact between the two countries. The visit is seen as a move by the US to show support for Taiwan's democracy and independence, while China has warned of "consequences" for any interference in its internal affairs.
