Will China Take Over the World?

As far as I can tell, the Chinese are never assimilated by other cultures, but the other way around.

Consider: 

The Mongols killed as many Chinese as possible, and took over their empire.  About 50 years later, the conquerors are speaking Chinese, writing Chinese, and can barely ride a horse anymore.
 
The Manchu, a completely distinct people with unrelated languages, dress, religion come and conquered China again.  Today, even the Chinese can't tell between Manchurians and Han Chinese. 

Every civilization around China, even without direct contact has been heavily influenced.

Now, as more Chinese head overseas into foreign communities, forming tight, isolate packs amongst themselves, could it be possible that they will exert a large cultural influence over us?  They are within us, spreading their beliefs and way of thought, I'd even bet a good part of 4chan is Chinese-American.

Will one day, the world around us, the Internet, the signs on the streets be half in Chinese?  Will we adopt Chinese customs and ways?  Or will we RESIST?

Discuss.

The real worry today isn't countries invading ours or others (we've al seen how well THAT has fared when attempted by our american masters), but whose got teh monies. Todays power doesn't grow out of a barrel, todays power grows out of a factory.
What country has the biggest economy names the rules, and because of that, we'll all soon be speaking chinese. Not because we'll have guns pointed at us (which we will, but anyway), but because we WANT to talk chinese. Well, that or china makes english its foreign relations language.
But the point is that the countries that have strong economies export their culture. Just look at 40-80 America with it's Hollywood and all, and todays Japan. The strength of these cultures is only because of the strenght of their economies. And so will be China, too.
