There are definite parallels, but I think they relate more broadly to the general behavior of authoritarian states rather than being exceptional comparable as policies. ICE is currently being used as to scapegoat 'foreigners' using bureaucratic violations, real or just percieved, to justify expelling them from US territory, with probably the ultimate goal of extending this to citizens and the general operation of a secret police on US soil. I would compare this more to internal Israeli policy for the first few decades of its existence with regards to Palestinians - the goal is expulsion, using a legal gray area (that is, nonetheless, plainly and unambiguously morally abhorrent) to engage in a form of ethnic cleansing.

China's current policy resembles more the Residential Schools of the US and Canada in the 19th and 20th centuries, wherein the culture of a native society is stomped out by a mixture of violence, relocation, sterilization, and economic and political pressure, with the end-goal of either reducing their numbers to the point of being entirely marginalized or exterminated, or eliminating their culture and ethnic existence by force. Or else the Turkish treatment of the Kurds and other ethnic minorities in the mid-late-20th century. The goal is the destruction of the ethnicity itself, not just its removal from valuable territory.
