China has $3 trillion in reserves, and it's completely meaningless when stacked against their rapidly expanding pile of debt. China is one of the most indebted nations, and to keep their GDP growth going they have to keep adding ever larger sums of debt. The amount of growth they get from $1 of capital has crashed the last six years. It's obvious how it's going to end: either in a very long period of dire stagnation, or crash.
