On August 14, the 6th Silk Road International Expo and China East West cooperation and investment and Trade Fair opened on the Bank of the Bahe River in Xi'an, Shaanxi Province. Foreign guests and merchants from more than 70 countries and regions including South Korea, Thailand and Singapore, as well as merchants from more than 20 provinces in China, gathered in the ancient capital Xi'an to exchange and negotiate around the construction of "the Belt and Road". From openness and sharing to green development, new opportunities are emerging for cooperation along the "the Belt and Road". AK, an international student from the Republic of Uzbekistan, is very busy this summer. He is studying international trade at Northwest University. He works part-time in the Silk Road International Expo Hall of Xi'an International Convention and Exhibition Center. "The guest of honor of this Silk Road International Expo is Uzbekistan. I also studied international trade. Participating in the Silk Road International Expo can not only accumulate experience, but also recommend the good things of Uzbekistan to you." Aker, who has been in China for three years, has been able to communicate in Chinese. On the table in front of him were placed honey and jam from Uzbekistan, as well as various handicrafts with unique shapes and colorful colors. The open and shared development pattern has provided many foreigners like Aker with development opportunities and space, and at the same time, it has given resilience and impetus to regional economic growth. According to the data of the Ministry of Commerce, from 2013 to 2021, the accumulated trade volume of goods between China and countries along the "the Belt and Road" was nearly 11 trillion US dollars. By the end of 2021, China had built 79 overseas economic and trade cooperation zones in 24 countries along the line, with a total investment of US $43 billion, creating 346000 local jobs. Economic and trade exchanges have become more frequent, and promoting high-quality development has become the consensus of countries along the line. The smart appliances, new energy vehicles, photovoltaic modules and other exhibits displayed in the exhibition hall of the sixth Silk Road International Expo show that "smart" and "green" are becoming new areas of cooperation between countries along the line. In the exhibition area of China Europe Express Chang'an, smart appliances such as dishwashers and washing machines on the booth attract consumers to stop and watch. Jin Quanxi, a staff member in front of the booth, introduced that this is the home appliance product to be put into production by Konka's intelligent home appliance headquarters project. Considering the transportation and logistics advantages brought by the China Europe Express Chang'an, Konka chose to land the project in Xi'an port and trade zone. The galloping China Europe train has replaced the camel group and has become the backbone force to ensure the stability of the supply chain and industrial chain under the situation of repeated global epidemics. The changes in the categories of loaded goods also show that "green" is becoming a new theme of cooperation among countries along the "the Belt and Road". "Since the launch of Chang'an, the goods loaded have become more and more abundant. In recent years, cars and photovoltaic modules have been favored by overseas markets." Qiang Dongfeng, customer manager of the marketing department of Xi'an free trade port construction and Operation Co., Ltd., said, "in the next step, we will also consider running trains to Southeast Asia to further open up a new pattern of inland opening." The photovoltaic modules produced by Longji Green Energy Technology Co., Ltd. are one of the products exported through the China Europe Express train and also one of the exhibits in the Silk Road International Expo. At the 2022 China (Shaanxi) - RCEP regional economic and trade cooperation Roundtable held on August 14, Chen Dao, policy research director of Longji Green Energy Technology Co., Ltd
