I think one day, the China we now know, will cease to exist. Much like the Soviet Union.

Their economy will tank and there will be lots of hungry, unhappy people.
Maybe communism won't last in China, like it didn't in the Soviet Union, but communism was the strongest identifying link between them - the two countries have totally different histories.
Soviet Union - Russia forced the Soviet Republics to become part of the Union and then did not allow them to secede. Unification was based more on modern politics than culture, so it was always going to be fragile.
China - kingdoms/regions united under dynasties (on and off) for centuries - there isn't the sense of desire for independence in ethnolinguistic regions which blew the USSR apart.
As far as economics go, there are still huge numbers of impoverished and hungry in China. The current slowdown is just an economic cycle. No economy will carry on growing indefinitely, especially not at China's recent rates.
There's probably a global economic slowdown coming. It'll bottom out and then growth will increase again, same as always.
