The deep cooperation between China and the world must be realized by means of China’s frontier areas—China’s land and sea areas. China’s land and coastal areas are China’s leading areas to the world，and they are the important lines of convergence and connection between the “Belt and Road” Initiative to coordinate the two major domestic and international situations. With the gradual promotion and deepening of “Belt and Road” Initiative，the role played by China’s frontier needs to be carefully studied. The “Belt and Road” Initiative is an important platform and carrier for the development of China’s frontier areas，and the development of China’s frontier areas needs to be realized under the framework of “Belt and Road” Initiative. The China’s frontier areas is an important space to realize the “Belt and Road” Initiative and fit with the surrounding international environment. We should focus on and study the opportunities of depth cooperation between the frontier and the neighboring countries and regions，and we also need to focus on and study the risks at the same time. The development of China’s frontier areas is an important part of China’s development and a major problem that the Chinese government has been focusing on to solve. The regional economic cooperation between China’s frontier areas and its surrounding environment is not only friendly，sincere and beneficial to surrounding countries and regions，but also can realize their own development and prosperity through mutual cooperation.
