The chinese economy is about 20% of the size of the US economy, I mean its impossible for them to pull us out of this.
Europe and America alone are 10 times as big as the chinese economy. Europe and America are bigger then all Asia economy put together. So, there is no way China can pull us out of this.
They can help, and they can help themselves and they are, but what they are doing may turn out to be good things for China.
I certainly expect China to come out of the recession sooner then the US, after all China has gigantic savings, reserves, they have the largest foreign exchange reserves in the world.
They have saved all that for a rainy day and now they are starting to spend it. For waht I can gather, they seem to be spending the money on the right things: infrastructure, projects that will help them to be more competitive if and when we get out of this crisis.
