Hehe, the external value of RMB reflects its exchange rate. At present, the international monetary system is Jamaica Accord, that is, floating exchange rate. At present, China implements a package of monetary policies and adjusts the exchange rate according to the value of other currencies. In the previous Bretton Woods system, when the exchange rate was fixed, it was the agreement of several countries to determine the value of the currency, which is what you said. A country can't control its own currency, which generally doesn't happen. Only some small countries adopt dollarization, that is, they don't have their own currency.

The key is to find out whether the China administration said that the RMB in 6 yuan changed 1 USD in 6 yuan RMB into 1 USD in 8 yuan RMB and 1 USD in 8 yuan RMB. So other countries that trade with China will not oppose or influence China's monetary policy?

This situation is that the exchange rates of all countries are basically linked to the US dollar. If the exchange rate of US dollars against RMB changes, their exchange rate against RMB will also change, which requires an agreement between countries. .
