Why is China building up their military so much??

Have they run out of manufacturing jobs? Will they invade Taiwan?
Does building up their military also constitute satellites as well?

I like Razors answer but not only do they want to be like the U.S i personally think they want to own the U.S. We have so much money going into a large, populated, communist country and when a country has cash and desire for power what do you think they will do? (Just in case you didn't know what i meant by so much money going in, companies like Walmart and all those "Made in china" companies are paying to get their raw materials there since its cheaper.) Plus when we first started trading with China it is their leaders to quoted this "The Americans are giving us the rope that we will hang them with." Meaning we are supplying our own death. Of course we see Bush and the Chinese leader having a little dinner and chat here and there but I believe that Bush is doing it to stay on their good side. The country is pretty poor right now but when it might become one of the most powerful countries in the next 20 years??? Most people don't want to believe it and don't give me a thumbs down just because you don't agree. Thats just what i heard and partly my reasoning. But if you think in this decade, what does a poor country want most? A good military of which it can conquer with. History seems to be repeating itself (The German Nazi empire after the depression and WW1). Plus, China has been picked on a lot. It has a good reason to do so.

~Brian M's answer is just proving my point even more, I do agree that the first world wars have a big part to do with it. If like gives you lemons, you squirt them in your enemies eyes. That may seem childish but its true. With a little bot of modernism they possibly might be able to take over the world. Don't buy stuff from Walmart!!!

China is more concerned with the actions of North Korea just like the rest of the world.
they wanna be like the USA
because they are quickly becoming a superpower and in order to be a superpower you must have a means of protecting your import, export and manufacturing. also N. Korea is gettin kinda bitchey down there
Unfortunately, nation/state capitalism requires war to settle the competition issues involved between differing nations in the acquiring of rights to natural resources and the control and domination of trade routes. As China become an economic power, capitalism will naturally force them to become a military power. The end result will be another world war. In fact, the real causes behind WWI and WWII rested on this very issue.
They build their Military in Peace, pay no attention to the satellite killing missles, nuke subs, MIG fighters, technology sold to them by the Clintons...by developing such things there is a techno trickle down to the toasters and action figures they make for Wal mart and Home Depot....you don't think they want to kill us and take over sears , do you??? Your Paranoid...Go back to the TV...
