You can't take imports/GDP or imports/reserves for China and extrapolate steady. China was an oil exporter until very recently and has just started to become a net importer. So you need to look at the predicted imports which are going to become much bigger very quickly.

Plus, the big problem for China is that this country cannot just hold steady and be content, the way, I believe, India could do. Its social compact requires it to grow fast and faster. If it stops, God knows what is going to happen...
