Russia may not want to miss the opportunity to provide open space for Bitcoin mining in their country since they have areas with cold temperatures and abundant energy resources, it will be one of the investment destinations for global Bitcoin mining companies. This wise move by Russia can have an economic impact on them with the influx of investment and taxes from Bitcoin mining companies, and especially the US is unable to sanction them in this case since Bitcoin is decentralized.
Bitcoin is gaining more wins each day on every side, The world is now realizing more on how they needed bitcoin, especially by people and region it had been wrongly talked about, the BRICS is the main target now.
But maybe specifically for China, they still can't fully accept Bitcoin in their country because they are quite protective and nationalistic about their currency and economy, so maybe Bitcoin still won't be fully accepted in China in the next few years. But maybe there is a change in that, although the possibility is small.
