Will China collapse into another civil war? I doubt it. They are doing very well, managing to hold a decent grip of power, while slowly giving more liberties to their people.

Their economy is very good, but has suffered a small collapse with a crash of their stock markets recently, but they will easily pick up from that, and probably emerge the strongest again, as their stock market crashing affects all other countries in the world, because the trading and loaning system is so intertwined.

Their environment is indeed terrible, and if they don't sort that out they're going to have serious problems.

Another competitor that might be able to challenge China is the EU, if they manage to unite, but I highly doubt they'd manage to do this quick enough.

EU challenge China? Your kidding, right?

EU has a terrible economy. Greece will eventually be shown the door. That COULD lead to spain and italy leaving. Spain, Italy, Frace, Portugal all have bad economies.

Germany is the only true economic power in the EU (except Britain, and Britain doesn't even use EU currency).

The EU does not have a terrible economy. It actually has a very good one, better than America's but not better than China's. If they unite, they need to turn into an even bigger (I quote Colonel) "A big socialist machine". So they can manage to distribute the wealth more evenly across this potentially future nation. Greece has a terrible, terrible economy right now, and there is no help, other than if they accept donations and bailouts. Why exactly would Spain and Italy leave? That is ridiculous. Spain would not be sustainable without the EU, and Italy is not too too much better. France has a very good economy, bigger than the UK's however it is slowly declining. Portugal, Spain indeed have bad economies. Italy is more robust economically than you might think.

If EU were to unite, Britain would have to end up using the euro, because it would be impossible to run a nation that is disunited fiscally, like the EU is right now, and that is causing problems still, but they'd be even worse as a single country.

EU has a terrible economy.

With just 7% of the world’s population, the EU's trade with the rest of the world accounts for around 20% of global exports and imports.

Around two-thirds of EU countries’ total trade is done with other EU countries.

Trade has been hit by the global recession, but the EU remains the world’s largest player accounting for 16.4% of global imports in 2011. The EU is followed by the United States with 15.5% of all imports, and China with 11.9%. The EU was also the biggest exporter, accounting for 15.4% of all exports – compared with 13.4% for China and the 10.5% for the United States.
