中国需主动消除与世界隔绝，无国家能承受孤立

No country can afford to isolate itself from the world. China needs to take initiative to eliminate the barriers that exist in the global economy, such as tariffs and non-tariff barriers. China should also promote trade liberalization and facilitate cross-border investment by establishing more free trade agreements with other countries. This will not only increase foreign direct investment into China, but also create more business opportunities for Chinese firms abroad. In addition, China should continue its efforts in developing high-tech industries and encouraging innovation so as to enhance its global competitiveness. Moreover, it should open up its markets further and actively engage in international organizations like the World Trade Organization (WTO) so as to ensure a level playing field for Chinese firms on the international stage. Finally, by strengthening its collaboration with other countries through dialogue and mutual understanding, China can help build an open global economic system that benefits all parties involved.
