China’s National People’s Congress passed an ethnic unity law on March 12, 2026, that makes Mandarin the required language of instruction in all schools, starting from preschool. The law also requires parents to teach their children to “love the Chinese Communist Party.” It passed by a vote of 2,756 to 3, with 3 abstentions, and takes effect July 1, 2026.
The ethnic unity law, as it is called, replaces an older legal framework that, at least on paper, protected the rights of ethnic minorities to use their own languages in schools and government. Under the previous rules (the 1984 Regional National Autonomy Law), schools in regions with large minority populations could teach in Uyghur, Tibetan, or Mongolian. The new law eliminates that flexibility.
In practice, Beijing has been enforcing Mandarin-only schooling in minority regions for years. In 2020, ethnic Mongolian families boycotted schools across Inner Mongolia after the regional government ordered Mongolian replaced with Mandarin in core subjects. In Xinjiang, Uyghur-language education has been dismantled alongside what the United Nations has described as possible crimes against humanitySerious crimes such as murder, torture, or persecution committed as part of a widespread or systematic attack directed against a civilian population.. In Tibet, a shopkeeper named Tashi Wangchuk was sentenced to five years in prison in 2018 simply for advocating Tibetan-language education in a documentary.
The new law takes what was happening informally and makes it legal obligation. It also goes further: parents who “instill in minors ideas detrimental to ethnic unity” face legal consequences, though the law does not define what that means. One provision even claims jurisdiction over people outside China who are deemed to undermine national unity.
Why does the language of schooling matter so much? When children are educated exclusively in a language that is not spoken at home, the home language declines. Linguists describe this as “language shiftThe process by which a community gradually replaces its heritage language with a dominant one across generations, typically completed within three generations as younger speakers adopt the dominant language.,” and it typically plays out over three generations. The first generation speaks both languages. The second understands the heritage languageA language tied to a person's ethnic or cultural background that is not the dominant language of education or public life, typically learned at home rather than at school. but defaults to the dominant one. The third speaks only the dominant language. By starting Mandarin-only instruction at preschool, before most children have fully acquired their first language, the law accelerates this timeline.
Human rights organizations have condemned the law. Maya Wang, deputy Asia director at Human Rights Watch, called it “a blatant effort by the Chinese government to control people’s thoughts and expression about China both inside and outside the country.” Erika Nguyen of PEN America said the law “targets spaces where children are most likely to encounter their mother tongue,” with the purpose of severing “children’s ties with their identity, history, and culture.”
No foreign government has announced sanctions or formal diplomatic consequences in response to the law. The gap between stated strategic interests and enforcement is a recurring feature of alliance politics. The United States, European Union, and United Kingdom have previously sanctioned Chinese officials over Xinjiang. Whether this law triggers additional measures remains to be seen.
The vote was 2,756 to 3. In a body of nearly 3,000 delegates, three voted no.
China’s National People’s Congress adopted the Law on Promoting Ethnic Unity and Progress on March 12, 2026, by a vote of 2,756 to 3, with 3 abstentions. The ethnic unity law mandates Mandarin as the principal language of instruction across all educational institutions, requires preschool children to begin learning Mandarin, and obliges parents to “educate and guide minors to love the Chinese Communist Party.” It takes effect July 1, 2026.
The law codifies in statute what Beijing has enforced informally for years across Uyghur, Tibetan, and Mongolian communities: the systematic replacement of minority-language education with Mandarin-only instruction, and the embedding of Communist Party ideology into every level of schooling and family life.
What the Ethnic Unity Law Actually Says
The law contains 62 articles. Several are worth reading carefully.
Article 15 requires that educational institutions use Mandarin as the principal teaching language. Children must begin learning it in preschool. By the end of compulsory education (typically age 15), they must have “basically mastered” it. This replaces the framework established by the 1984 Regional National Autonomy Law, which guaranteed ethnic minorities the right to “use and develop their own spoken and written languages” and allowed schools in minority regions to use local-language textbooks and instruction.
Article 12 directs the state to “organize education” promoting “correct views of the state, history, nation, culture and religion.” In practice, this means one interpretation of all five subjects, defined by the Party.
Article 20 is where the law enters the family home. Parents must “educate and guide minors to love the Chinese Communist Party” and are prohibited from “instilling in minors ideas detrimental to ethnic unity and progress.” The law does not define what constitutes such ideas. That ambiguity is not an oversight.
Article 14 directs authorities to “establish and highlight Chinese cultural symbols” in public spaces and tourist sites, including through place naming. Article 40 promotes “the transformation of customs and habits” regarding marriage, effectively discouraging ethnic or religious-based practices. Article 44 mobilizes enterprises and public institutions to promote Party ideology.
Article 61 extends the law’s reach beyond China’s borders, holding “organizations and individuals outside the People’s Republic of China” legally accountable for undermining national unity.
What the Ethnic Unity Law Replaces
The 1984 Regional National Autonomy Law was not generous. It was, by Western standards, a limited document that granted conditional rights within a one-party framework. But it did contain explicit protections for minority languages in education and governance. Schools in autonomous regions could use minority-language textbooks. Local governments could conduct official business in local languages.
The new ethnic unity law does not formally repeal the 1984 law. It supersedes it. Where the earlier law said minority students should learn Mandarin, the new law says Mandarin is the medium of instruction. Where the earlier law allowed flexibility in when minority students began Mandarin study, the new law starts at preschool. Where the earlier law was silent on ideological requirements for parents, the new law makes Party loyalty a parental obligation.
Yalkun Uluyol, a China researcher at Human Rights Watch, described the legislation as a “significant departure” from the Deng Xiaoping-era policy framework that had, at least on paper, guaranteed minority language rights.
What Was Already Happening Before the Law
The ethnic unity law does not create a new policy direction. It provides legal backing for one that has been accelerating for years.
In Inner Mongolia in August 2020, the regional Department of Education ordered ethnic schools to replace Mongolian with Mandarin as the language of instruction in three core subjects: language and literature, civics, and history. Tens of thousands of ethnic Mongolian students boycotted classes in response. At one school in Naiman Banner, according to BBC reporting at the time, only 40 of the usual 1,000 students registered for the semester. The protests were suppressed. The policy remained.
In Xinjiang, the replacement of Uyghur-language education with Mandarin instruction has proceeded alongside the broader “Strike Hard Campaign” against what Beijing calls extremism. The United Nations Office of the High Commissioner for Human Rights concluded in a 2022 assessment that China’s treatment of Uyghurs in Xinjiang may constitute crimes against humanitySerious crimes such as murder, torture, or persecution committed as part of a widespread or systematic attack directed against a civilian population.. Beijing rejects this characterization.
In Tibet, advocacy for Tibetan-language education has been treated as a threat to ethnic unity for over a decade. Tashi Wangchuk, a Tibetan shopkeeper who appeared in a 2015 New York Times documentary advocating for Tibetan-language education, was sentenced to five years in prison in 2018 on charges of “inciting separatism.” The pattern of selective international response to state-led persecution of minorities is well documented.
A joint report by PEN America and the Southern Mongolia Human Rights Information Center documented that nearly 89% of Mongolian-language websites reviewed in China have been censored, converted to Mandarin-only access, or stripped of cultural content.
What Rights Groups Are Saying
Maya Wang, deputy Asia director at Human Rights Watch, called the law “a blatant effort by the Chinese government to control people’s thoughts and expression about China both inside and outside the country.” She warned that “Tibetans, Uyghurs, and others who speak out for minority populations can expect even greater government repression.”
Erika Nguyen of PEN America said the law “targets spaces where children are most likely to encounter their mother tongue,” arguing that its purpose is to “sever children’s ties with their identity, history, and culture.”
Enghebatu Togochog, director of the Southern Mongolia Human Rights Information Center, warned that the law “marginalizes Mongolians, as Chinese fluency becomes a gatekeeper for jobs and advancement.”
The Congressional-Executive Commission on China characterized the law as escalating a “systematic campaign to assimilate ethnic minorities” through policies that hollow out legal protections. The CECC noted that the law potentially violates China’s obligations under the International Convention on the Elimination of All Forms of Racial Discrimination, which China ratified in 1981.
The Mechanism: How Language Policy Becomes Cultural Erasure
Language policy might seem like an administrative matter. It is not. When a government mandates that all instruction occur in a single language starting at age three, it does not merely add a skill. It restructures which language children think in, dream in, and eventually raise their own children in. Linguists call this “language shiftThe process by which a community gradually replaces its heritage language with a dominant one across generations, typically completed within three generations as younger speakers adopt the dominant language.,” and it typically takes three generations to complete. The first generation is bilingual. The second understands the heritage languageA language tied to a person's ethnic or cultural background that is not the dominant language of education or public life, typically learned at home rather than at school. but speaks the dominant one. The third speaks only the dominant language.
China’s ethnic unity law accelerates this process by starting Mandarin-only instruction at preschool, before most children have fully acquired their first language. It then reinforces it by making Mandarin fluency a requirement for completing compulsory education, which in turn determines access to higher education and employment.
The law does not ban minority languages. It does not need to. By removing them from the one institution where children spend most of their waking hours, it ensures their decline without a single prohibition on paper.
What Comes Next
The law takes effect on July 1, 2026. Implementation will fall to provincial and local governments, many of which have already been enforcing its provisions informally for years. The gap between the law’s text and its effects will be measured not in legal challenges (China’s judiciary does not operate independently of the Party) but in the speed at which minority-language fluency declines among the generation now entering school.
No foreign government has announced sanctions or formal diplomatic consequences in response to the law’s passage. The gap between stated strategic interests and enforcement is a recurring feature of alliance politics. The United States, European Union, and United Kingdom have previously sanctioned Chinese officials over Xinjiang. Whether this law triggers additional measures remains to be seen.
