China is set to pass a law on a "shared" national identity among the country's 55 ethnic minority groups, a move critics argue will further erode the identity of people not majority Han Chinese. The law, named "Promoting Ethnic Unity and Progress", aims to forge national unity and advance the rejuvenation of the Chinese nation. It also aims to promote integration across ethnic groups through education, housing, migration, community life, culture, tourism, and development policy. It mandates Mandarin as the basic language of instruction in schools and for government and official business where Mandarin and minority languages are used together. Critics argue that this could make anyone challenging this unity a separatist.
