The statistical data from The World Bank: China could overtake the United States this year , which may won the crown of the world's top economies

I am reading newspaper, and one of the news is really scared me. just like a two side coin, I think the growth of China economics is not that good,maybe. Becoming the top of the world means a lot of responsibility. China is sooo poor( per capita GDP is ninety-ninth in the world ) and I dont think we can take it.However, there are some benefits, too. Developed countries will draw attention to China, its doing good to our export. So, what do you think? I need your opinion so badly!
