The People's Bank of China authorized the China Foreign Exchange Trading Center to announce that the central parity of the US dollar against RMB in the inter-bank foreign exchange market in June 5438+1October 65438+February 2009 was US$ L. C

Choose C, the appreciation of RMB will increase the purchasing power of RMB in the international market, while the purchasing power of USD in China market will decrease. It can be seen that the appreciation of RMB is beneficial to China's imports but not to its exports. It is beneficial to China's foreign investment, but it is not conducive to foreign investment in China, so ② ③ is correct. ?
