Ever since China implemented the new economic reform policy in late 1978 and opened its door for foreign investments, United States and other countries have established manufacturing facilities in China to take advantage of its cheap and skilled labor forces. Over the years, China has accumulated large foreign exchange reserves as a result of its ever increasing exports to the US as well as to the rest of the world. In turn, China has used this wealth to reinvest in US Treasury bonds , real estates , and businesses .
All these activities promote closer personal relationships between the two countries. English has long been a second language of choice for most Chinese citizens. Most Americans begin to find that being able to understand and speak Chinese provides a valuable social skill as well as better job opportunity.
