The US dollar crisis continues, the exchange rates of major currencies fluctuate frequently, the international capital market develops rapidly, the international liquidity expands rapidly, and the reserve assets lack proper international management. The fundamental reason is that the relative economic status and strength of the United States and other industrial countries have changed greatly.
