Since 200 1, the Bank of China has been desperately storing US dollar currency. By 2007, China's foreign exchange reserves reached $65,438 +0.53 trillion. China does not have any global basic commodity reserves. In 2007, the dollar index plummeted to 80; Oil prices soared to $90.

However, many people in China will point out that the central banks of the United States and China "do the opposite". That is, the Bank of China reserves a large amount of oil instead of dollars. Then, the oil price plummeted and the dollar index rose sharply.
