You mean $4 trillion, right? The role of foreign exchange reserves is to promote international market transactions. After all, 95% of the world's foreign exchange reserves seem to be settled in US dollars, and the source of 4 trillion is mainly the hard work of the domestic people. As the so-called "Made in China" has spread all over the world, a large surplus naturally brings a large amount of foreign exchange reserves. The larger the amount, the more stable China's exports will be, but excessive foreign exchange reserves will also bring problems. If it is released to China, it will easily lead to currency overshoot and inflation (including the RMB rising from the outside to the inside since the financial crisis in 2008).

Therefore, China's economic transformation is more about locking the wealth of China people at home. How to do this? Economic restructuring and industrial upgrading are all macro aspects, the essence of which is to improve scientific and technological capabilities, product quality and added value, so that China manufacturing is not a global pollution but the pride of China!

As far as politics is concerned, American hegemonism threatens every country all the time, so it is meaningless to judge politics or advantages and disadvantages simply from any single index such as foreign exchange reserves. Understand the core of money and the foundation of the country! You will know that China is constantly resisting the attack of the United States (western countries, led by the United States) in currency, military and even food and clothing! Please be proud that you are from China! Even if it is not now, it will be in the future 10 -20 years! !
