Problem with China economic boom

China is a country that has a huge economic growth, it is said to be one of the biggest producer in the world. China is rich in raw materials and also large number of population, probably a little more or less than India. Because it is so rich of resources such as natural resources, they don't cost much money and everything is cheap as their life expectancy doesn't cost so much. The foreigner then saw their opportunity of making a profit , by investing in China.

Because everything is cheap, including a factors of production and also cheap labor , China attracted many investors around the world to invest in their country, brings up their economic growth and the Chinese also developed their technology by learning from the foreigner, creating a good engineer to help the country developing even more.  

Now what's the problem with China having a good economics? what is that to do with US's economic?
It is because China's currency is so cheap, even cheaper than the US and is remaining low no matter  what global's economic status are, Renminbi is still low. This causes more and more investor to go investing in China rather than their country because of their economic issues. So, more foreign investors in China is equal to less local investor in other countries, causing a local people to lose their job. These problems are causes by the stable currency in China, taking all the investor to their country.

This is why almost every time we look under our household equipments or furnitures, it usually labeled "Made in China", because they have the most businesses invested in their country . China is leading in production because the investor could offer a small wages and in return, a high quality goods , also cheap cost of production which means more profit to the company.

These are just a clarification of the Economic Boom, which is a big problem to the whole globe as other countries (that aren't rich in resources nor cheap labor) thought it was unfair and wanted the Renminbi to go up according to the economic movements, because if this is still going then it will sure to causes more trouble to world's economies.

Further question : How does the economic boom in China effects other countries?
