China is the country with the largest population in the world at over 1.3 billion people. The land covers approximately 3.7 million square miles. The country is governed as a communist country, although they have developed a quasi-capitalist sector for business. China has the second largest gross domestic product (GDP) at approximately $7.0 trillion; behind the U.S. at $15.0 trillion and ahead of Japan at $5.8 trillion. The leaders opened up the centrally planned economy in the late 1970s and early 1980s to allow economic growth through trade, which has allowed China to grow at an unprecedented rate for a country its size. From 2001 to 2011, China grew at an annualized rate of 10.5%.
