The 14th China Northeast Asia Expo is being held in Changchun, Jilin Province. This Expo has attracted thousands of enterprises from more than 40 countries and regions to participate in the Expo. Some participants and experts believe that the "the Belt and Road" is bringing great vitality to the revitalization of Northeast China. As one of the series activities of this Northeast Asia Expo, the "the Belt and Road" Initiative to Expand the Northeast Circle of Friends was held in Changchun by the "the Belt and Road" National Business Association. Representatives of business associations and government agencies from 13 countries along the "the Belt and Road", including Nigeria, Comoros and Ethiopia, came to Jilin to promote exchanges and cooperation with Jilin in agriculture, energy and other fields. Northeast China is China's traditional equipment manufacturing base. In recent years, it has deepened its development in green energy, rail transit manufacturing and other fields, which has also allowed some businessmen from countries along the "the Belt and Road" to see opportunities for cooperation. Johnson Anene, Chairman of the Abuja Trade Center of the Abuja Chamber of Commerce and Industry in Nigeria, stated that Nigeria is accelerating its development in areas such as construction, mining, tourism, manufacturing and transportation, and logistics infrastructure, which have many investment opportunities. As an important window for China's "the Belt and Road" opening to the north, the scale of import and export trade between Jilin and the countries along the "the Belt and Road" has been expanding, and local competitive industries have been better integrated into the global industrial chain. According to Li Qingchen, president of CCPIT Jilin Council, based on local competitive industries, Jilin has carried out multi-channel, multi-level and multi field economic and trade activities with countries along the "the Belt and Road", greatly improving the level of connectivity with countries along the "the Belt and Road", and expanding the "circle of friends" for economic and trade cooperation.

Wang Yue, the chairman of Changchun International Land Port Development Co., Ltd., which operates this line, introduced that the China Europe Express ("Chang Man Europe") starts from Changchun City, Jilin Province, exits through the Manzhouli Railway Port, passes through Siberia, Belarus, Brest, Warsaw, Poland, Nuremberg, Germany, and other places, and deepens into the hinterland of Europe. BMW, Audi, and other German automotive components are shipped from Europe to Northeast China. The automotive and electromechanical products produced in Northeast China are transported to Europe through the China Europe freight train, and the participation of the old industrial base in the global economy in Northeast China continues to increase. Experts believe that Northeast China is strategically located in Northeast Asia and has good conditions for opening up to the outside world, such as Japan, South Korea, and the Far East region of Russia. It is suggested that the Northeast seize the opportunity to promote cooperation with Europe and absorb advanced elements through the "the Belt and Road" channel.
