Beijing —

For years, Chinese leader Xi Jinping has pushed ethnic minority groups like Tibetans and Uyghurs to adopt an identity rooted in Chinese nationality and allegiance to the ruling Communist Party.

Now, that push has been codified into a sweeping new law that reaches into classrooms, neighborhoods and homes – and gives Beijing the right to target people outside of its borders that it believes violate its rules.

The statute, officially known as the Ethnic Unity and Progress Promotion Law, came into effect on July 1. It bans acts that “undermine ethnic unity or create ethnic division” among China’s 56 officially recognized ethnicities, which include a Han Chinese majority that makes up over 90% of the country’s 1.4 billion people.

Under the new rules, schools and government agencies must use Mandarin Chinese as their primary language; classrooms must ensure that their curriculum “forges a strong sense of the community of the Chinese people,” and all parents must guide children to “love the Chinese Communist Party and the Chinese people.”
