It is very important to open to the outside world. No country can develop in isolation, with its doors closed; it must increase international contacts, introduce advanced methods, science and technology from developed countries and use their capital.

• 对外开放具有重要意义，任何一个国家要发展，孤立起来，闭关自守是不可能的，不加强国际交往，不引进发达国家的先进经验、先进科学技术和资金，是不可能的。
