Save for later Print Download Share LinkedIn Twitter US House Speaker Nancy Pelosi’s visit to Taiwan this week has brought to the fore the most contentious issue in the US-China relationship: Taiwan. Beijing considers it a renegade province that will ultimately be reunited with the mainland. The US, despite signing onto the "one-China" principle that recognizes the People’s Republic of China as the only legitimate Chinese government, has kept unofficial ties with Taipei and supplied it with arms sales for self-defense. Pelosi’s visit came with fears of “Ukraine today, Taiwan tomorrow” in the background after Russia invaded Ukraine in February, bringing renewed attention to Taiwan at a time of growing Chinese overreach.
