The big picture in the Indo-Pacific - Taiwan, China, and the USA

Context

The Speaker of the United States House of Representatives arrived in Taiwan on Tuesday for what she called a show of American solidarity with the island, defying repeated warnings from Beijing and fuelling a new round of US-China tensions. 

What is One China Principle and One China Policy?

• One China Principle- It is a core belief that sees Taiwan as an inalienable part of China, with its sole legitimate government in Beijing. The US acknowledges this position but not necessarily its validity.
• One China Policy -Meaning that the People's Republic of China (PCR) was and is the only China, with no recognition for the Republic of China (ROC, Taiwan) as a separate sovereign entity. At the same time, the US refuses to give in to the PRC’s demands to recognise Chinese sovereignty over Taiwan — it only acknowledges the Chinese position that Taiwan is a part of China.
• Approach by different countries- The PRC follows the One China Principle whereas The US instead follows the One China Policy. The US has stuck to this position ever since — and used the “strategic ambiguity” that it creates to maintain the status quo and preserve stability in the Taiwan Strait.
