1. Equal opportunity for trade and investment: All countries should have the same opportunity to trade with and invest in China, regardless of their size, economic strength, or political system.
2. Non-discriminatory treatment of all countries: China should not discriminate against any country in terms of trade or investment. This means that China should not impose tariffs, quotas, or other barriers to trade that are specifically designed to hurt a particular country.
3. Respect for China's sovereignty: The Open Door policy does not call for China to give up its sovereignty or to allow foreign countries to interfere in its internal affairs. However, China should respect the rights of other countries to trade with and invest in China.
The Open Door policy has been controversial since it was first proposed. Some people believe that it benefits the United States and other wealthy countries, while it hurts China and other developing countries. Others argue that the Open Door policy has helped to promote economic growth and development in China and other countries, and that the benefits of the policy outweigh its costs.
Regardless of the controversy, the Open Door policy remains an important part of the United States' foreign policy towards China. The policy has been endorsed by numerous U.S. presidents and administrations, and it is likely to continue to be a part of U.S. policy for the foreseeable future.
