In recent years, China's manufacturing industry has developed vigorously, exports have grown rapidly, trade surplus has increased substantially, and the country's foreign exchange reserves have naturally increased rapidly.

It should be pointed out that such a large trade surplus is inseparable from China's basic monetary policy. The RMB has been slowly appreciating against the US dollar, which has left some adjustment and adaptation time for export enterprises. Therefore, China's exchange rate policy is also an important factor in the surge of foreign exchange reserves.

It is precisely because of the rapid development of China in recent years and the financial crisis in western countries that many international capitals have flooded into China, which has also strengthened China's foreign exchange reserves.
