Data map: bank workers are clearing money. Zhang Yun Calov said that because the United States may continue to impose sanctions on Russia, the ruble is still facing greater pressure in the near future. But contrary to what Trump said, the Russian central bank is studying policies to ensure the stability of the ruble and the security of the Russian economy. Calov said no country would play games with its own currency. Trumps statement is indiscreet and irresponsible. Anastacia, a senior researcher at the Far East of the Russian Academy of Sciences, said that after Trump became president of the United States, he had more than one time exerted pressure on other countries through exchange rate issues. His practice had obvious political purposes. Anastasia said, since this year, the yuan dollar exchange rate remained stable, this is Chinese domestic good economic environment as well as the RMB market supply and demand determined. At the end of March there has been a slight fluctuation of RMB is also affected by the United States to provoke trade friction, the so-called play the game unfounded. Anastasia believes that in the current international monetary system, the dollar still occupies an important position, including the influence of the ruble and the yuan, the global currency were affected by varying degrees of American foreign trade and monetary policy. In this case, Trump should carefully examine his own policy and take a big responsibility for stabilizing the global exchange rate market and the trade environment. Witt Kopf, a senior researcher at the Russian Economic Strategy Research Institute, said that Russia and China, as a developing country, have the greatest benefit to maintain the stability of the exchange rate. Measures to intervene in the exchange rate, if affected by short-term goals or external pressures, will bring opportunistic and hype to other financial powers. Both the Russian and Chinese currencies can not withstand such a impact. Witt Kopf believes that the so-called play of the devaluation game between Russia and China is not in line with the actual situation, the political meaning is very obvious, it is worth vigilant.
