A recent period in the global trade protection intensified the agitation, persecute the yuan to appreciate by western and old tunes are familiar, Europe and the United States parties to put pressure on China's foreign trade of action, are faint but the upgrade. Why the United States and other western countries so keen on the appreciation of the renminbi? On the surface, the western countries in the indulgence of the us dollar, the euro depreciation of the also asked the appreciation of the renminbi, the main reason is nothing but in order to reduce China's trade deficit. But in fact, people's currency revaluation of the old tunes are familiar sight to transfer, shirk responsibility, let countries in the world, including China for America's huge trade deficit, fiscal deficit "bill". For getting rid of the financial crisis, the United States is using its dollar hegemony position, and the dollar as the convenience of currency valuation of international trade, and the implementation of the "the weak dollar" policy and set the weak dollar, and unreasonable demand other national currencies. Because the dollar is the biggest beneficiaries of the United States, the victims are all countries in the world and are fragile recovery of the global economy. There is no doubt that the appreciation of the renminbi adverse world economic recovery, because the current global economic recovery situation instability, the world's major economies exchange rate should not suddenly change. If China push sharply RMB exchange rate, will be a serious distortion of economic development of the normal track, western countries are not so reducing trade deficit, on the one hand, other manufacturing power will immediately fill the void left by China's manufacturing, a aspects to higher prices to import the necessary Chinese products, so the trade deficit would be expanded further. In addition, once sharp appreciation of the yuan in China because the economy was in the lowlands, the western countries in China for main market related enterprises will inevitably suffered heavy losses. So, forcing the appreciation of the renminbi to solve its problems is the practice of bad people, and to themselves, more not not fair. Theoretically, with trade flat; Judge in RMB exchange rate no meaning, in dollars in the international monetary system standard, bilateral trade break; Is the norm, never be the problem of exchange rate. From the reality of it is, currency exchange rate to improve surplus influence is very small, whether that year of Germany, or to the euro zone now for a whole, as well as countries such as Japan, continue for decades for American trade surplus trade status. These countries and regions against the us currency exchange rate mechanism is completely floating, but to improve bilateral trade break; No any for use. China's exports a lot of labor-intensive products, but China is only manufacturing process, in the western countries marketing link importers have gained much profit. China's foreign trade structure, economic structure need to adjust, but China and west side in different stages of development, structural problems facing the emphasis and difficulty is different, as the western need to strengthen financial supervision and change gradually excessive consumption habits, strengthen the entity economy, China also needs to step by step to the implementation of economic structure adjustment and reform of the exchange rate.
