Ethnocentric regimes are *loyal* to their ethnic group. This means they will always favour that ethnic group no matter what, even if it hurts the regime. Communist regimes use ethnic groups as pawns. One day that means they favour one, the next they favour another. That decision is based purely on pragmatism, not loyalty. A good example of this would be Lenin, who used the Russians to gain power, but planned to transfer the capital of his new socialist empire to Berlin if he gained power in Germany, as he preferred Germans. Stalin is another example, he was initially Russocentric, but later began showing preference to non-russian minorities in order to expand his powerbase and buy loyalty. Up until now it has been in the PRC's interest to show preference to ethnic hans, but that's beginning to change. Already they're internally virtue signalling about the importance of migrants and anti-racism. They know that the price of han labour is going to rise, but they don't want to make the mistake of outsourcing like the US did, so they're going to have to engage in population replacement to retain industrial power.
