The question is simple. There is an economic crisis in the United States, and the dollar keeps falling. If they convert it into RMB and convert it into US dollars after a period of time, they will get the price difference. China's foreign exchange reserves were trillions of dollars, and the dollar fell by 1 percentage point. How much do you think China lost? Now the United States has passed on all the negative effects and losses caused by the economic crisis to other countries, and China has become the number one creditor and the number one disaster relief country in the United States. When foreign consortia come to China, US dollars are first converted into RMB through the Bank of China. Therefore, the country knows everything. According to these, the country has also taken measures, such as issuing RMB, which is a good way. If foreigners hold too much RMB, there will be fewer domestic people and less money, which will easily lead to deflation. Therefore, it is necessary to issue RMB.
