Russia is a regional power; they really lack the projection capabilities that the US and China have but they do make up for it by being relatively effective with regional or slightly removed regional conflicts.
basically the only two powers are the US and China now, and China relies a lot on the US trade to maintain their social structure.
If you think about where China was back in the 80s and how quickly they managed to develope in the last 30 years you get an idea how far they will bring it in the next 30 years.
Their big advantage is the big population. For a successful society you need smart guys, workers and so on. Chaina has more than enough from each of them.
