Wang Yuan, former chief economist of the China Development Bank, said at the "Sanya Finance and Economics International Forum" on December 8 that China's economic development and opening up are two-way, and we must open up to the world and go out. China's foreign investment is still a novice, in the process of investment, we should respect the market and cooperate with enterprises, "because the judgment of enterprises to the outside is still very correct, especially when financial institutions are financing, they should cooperate with enterprises to make market judgments, prompting national risks and regional risks." ”
