When Chinese authorities replaced Mongolian with Mandarin as the language of instruction for core school subjects in 2020, the move triggered the largest public protests Inner Mongolia had seen in decades. Six years on, the classroom fight is effectively over, and the campaign has followed Mongolian speakers into the one space they had left: the internet.
A report released in January 2026 by PEN America and the Southern Mongolian Human Rights Information Center documented the systematic removal of Mongolian-language content from Chinese online platforms – social media groups shut down, accounts deleted, and informal digital communities dismantled.
The findings are difficult to verify independently, as is much reporting from a region under tight information control. But the censorship fits a clear trajectory. The target of the linguistic crackdown is no longer Mongolian as a language of formal instruction. It is Mongolian as a living language of everyday life.
Notably, the careful deletion of Mongolian is targeting an ethnic group that has never posed a separatist or terrorist threat – the rationale the Chinese government uses to justify similar campaigns of cultural erasure in Xinjiang and Tibet.
The online deletions are the endpoint in a longer chain of events, where each step has narrowed the space for the Mongolian language a little further. In 2020, Beijing mandated that literature, history, and politics – the subjects that carry cultural transmission – be taught in Mandarin rather than Mongolian, recasting “bilingual education” from Mongolian-medium schooling with Mandarin as a subject into Mandarin-medium schooling with Mongolian as a subject. By 2023, regional authorities had ordered schools to complete the switch to Mandarin-only instruction and had cut weekly Mongolian classes sharply, including in kindergartens. The college entrance examination, the single most consequential test in a Chinese student’s life, is being steadily de-Mongolianized – the Mongolian-language gaokao has been phased out, and from 2026 the bonus points long awarded to ethnic Mongolian and other minority candidates are being halved, from 10 to five.
Each measure on its own can be defended in the language of opportunity, Mandarin proficiency, after all, is a real advantage in the Chinese labor market, which is precisely how officials have framed the reforms. The idea, apparently, is to let economic self-interest kill off any incentive to learn the language. But Beijing wasn’t done yet.
The digital campaign documented in the January report is the logical endpoint of this approach. Now that the Mongolian language has been pushed out of schools, exams, and official life, the places where it survives are informal and largely online: chat groups, content creators, and diaspora-linked communities where Mongolian still circulates. Removing that content closes the last venue where the language reproduces itself outside the home.
It is also consistent with a broader rebranding effort: a 2023 campaign reclassified Mongolian heritage as 边境文化, or “frontier culture,” a framing that absorbs a distinct identity into a peripheral variant of a Han-centered national story. References to Chingghis Khan have reportedly been pared back from museums and curricula. The aim is not merely to change the language the ethnically Mongolian people speak, but to alter the category their culture occupies.
What makes Inner Mongolia analytically distinct – and underexamined – is that none of this can be explained by the security rationale Beijing invokes elsewhere. Xinjiang and Tibet have been governed through the lens of separatism and unrest; the assimilation policies piloted there from 2017 and 2018 were justified, however unconvincingly, as counters to a perceived threat. Inner Mongolia offers no such pretext. It has no significant separatist movement, no record of organized violence, and a Mongolian population that is a demographic minority within its own autonomous region, long integrated into the Chinese state. The 2020 protests were a reaction to the policy, not a cause that preceded it.
This is why the region is the more revealing case for China’s ethnic policy. The extension of the same playbook to a compliant minority suggests that what is driving policy is not a response to instability but a proactive program. China’s “second-generation” approach to ethnic affairs favors fusion over accommodation, and treats the persistence of distinct minority identities as a problem to be solved rather than a reality to be managed. If the model is applied where there is no threat, then the threat was never the operative variable. The problem, from the Chinese government’s perspective, is the existence of difference itself.
There is a geopolitical dimension as well. Inner Mongolia is not a remote periphery; it is one of China’s most strategically weighted regions, anchoring much of the country’s coal and rare earth supply and forming the central segment of the China-Mongolia-Russia economic corridor. It also shares a long border with the independent state of Mongolia, where the treatment of ethnic kin across the frontier periodically stirs public sympathy. Beijing’s tolerance for any friction in this borderland is correspondingly low, and the steadiness of the assimilation timeline – advancing regardless of protest, censorship cycles, or international criticism – reflects a calculation that demographic and cultural consolidation of a critical region is worth the reputational cost.
For Ulaanbaatar, this presents a quiet dilemma that it cannot easily voice. Mongolia depends heavily on China economically, and has little leverage to object to the treatment of Mongolians across the border, even as its public watches a related culture being absorbed. That tension – genuine sympathy constrained by structural dependence – is one of the more honest illustrations of what asymmetric interdependence with China actually demands of a smaller neighbor.
There will be no second wave of mass protest in Inner Mongolia; the space for it has been deliberately closed, online and off. Instead, the more probable outcome is gradual and quiet: a generation of ethnic Mongolians who understand their grandparents’ language as a distant heritage rather than speaking it in daily life. The January report is a marker of how far that process has run, and a reminder that the most complete forms of erasure are the ones that meet the least resistance, in the places no one was watching.
