The fundamentals of the policy (I'm presuming your referring to 改革开放) is to open China to the global economy. The policy is to allow China to secure the advantages of foreign direct investment and trade flows (so, international flows of goods and capital) within the context of a more private market economy. What I mean is that the trade and investment flows are allowed within a changed domestic economy, one that relies more on the price mechanism and private, rather than mostly state-owened enterprises. It's a policy of economic reform, not one of political reform or the opening to foreign cultural and political influences.

Hello, Do you mean the open-up policy?

Can you write the Chinese? I dont understand the question.
