China is maybe one fifth the size of Europe's economy. China can't save the world, no matter what they do. They are investing in their own economy and have huge reserves and huge savings, The World Bank has predicted that in 2020, China will be the world's largest economy. But the World Bank has never been right about anything. It could well happen in the next 10 or 20 years, but on a per capita basis probably not within my lifetime, unless the U.S. really collapses and China really booms.
