I've seen many notable projections also about China and Russia no longer being countries by 2028 (eg splitting due to war or civil differences) which is something I think we'll see a large pressure on a split at some point (especially in china).
Not likely at all. The western world expected that China modernizing its economy and becoming more open would hasten the communist party's decline, but the opposite has happened. There is no internal pressure to break up the country or the party as long as the economy is improving the lives of citizens. The party is as strong as ever.
