New legislation will require schools to use Mandarin by default, taking priority over minority ethnic languages such as Tibetan, Uyghur and Mongolian

China’s National People’s Congress (NPC), the state legislature, will vote on Thursday on a suite of new laws agreed at this year’s annual two sessions gathering, including a piece of legislation that will diminish the role of minority ethnic languages in the education system.

NPC delegates are expected to approve a new ethnic unity law, along with a new environmental code and the 15th five-year plan, the economic planning document for 2026-2030. Delegates have spent the last week debating Beijing’s proposed bills, which they are all but certain to approve. The NPC, which is often described as a rubber-stamp parliament, has never rejected an item on its agenda.
