The British parliament has for the first time referred to Taiwan as an “independent country” in an official document, breaking a political taboo as Foreign Secretary James Cleverly visits China this week.

The new language, adopted in a report published Wednesday by the influential foreign affairs committee of the House of Commons, risks a stinging backlash from Beijing and comes as Cleverly becomes the first top British envoy to visit Beijing in five years amid a frosty relationship.

Beijing has long denied Taiwan’s statehood, insisting the self-governing democratic island is part of its territory. Only 13 countries around the world recognize Taipei instead of Beijing diplomatically.
