On July 1, 2026, the Law on Promoting Ethnic Unity and Progress officially took effect. Tibetan and Uyghur groups warned at the UN that the law legalizes cultural erasure, while UN human rights experts stated it could severely impact the linguistic, cultural, and religious autonomy of ethnic minorities.
On March 12, 2026, the National People's Congress passed the Law on Promoting National Unity and Progress, stipulating that schools and government agencies must use Mandarin as their primary language. From preschool to high school, Mandarin will be used for instruction, while Tibetan, Uyghur, and Mongolian are phased out of core curricula.
