About my research paper

I've spend many times to think about which topic do i pick,and its really hard to pick one topic that fit u very much.One day,when i was searching the internet.I thought a couple of news are talk about economy between China and United States,they are compare how effect to each others.I'm from China,so i thinking how about pick this topic as my research paper.The reason why i choose this topic as my research,because of the United States, the world’s leading debtor nation, is now heavily dependent on Chinese capital to underwrite its fast-growing debt. If China ever decides to divert this capital surplus elsewhere, either to internal investment or to the development of oil, gas, and mineral resources elsewhere in the world, the U.S. economy will be in trouble. otherwises,thats more easier than other topic,cuz u can find many news and comments online
