Assume that the current exchange rate of USD against RMB is 1: 8. China needs 80 million yuan (US$ 6.5438+million) to import a batch of soybeans from the United States.

The exchange rate of RMB against the US dollar appreciated to 1: 6. At this time, you only need 60 million yuan to import the same amount of soybeans.

Therefore, it can be concluded that the appreciation of RMB against the US dollar is beneficial to imports.

Suppose that the United States needs to import a batch of steel with a value of 1000000 yuan from China. When the exchange rate of RMB against the US dollar is 8: 1, the United States needs to pay1250,000 US dollars. However, if the RMB depreciates to 10: 1, the United States only needs to pay 100000 dollars.

Therefore, it can be concluded that the depreciation of RMB against the US dollar is beneficial to US imports, that is, to China's exports.

This is the impact of exchange rate on China's import and export. To sum up, RMB depreciation is beneficial to exports and RMB appreciation is beneficial to imports.
