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.

That's why the West needs to take steps to weaken the chink politburo. if we can get their slanty-eyed citizens to remove those assholes in charge, the govt will collapse and begin reform, and it'll take time to recover, like with russia.
