On March 21st, at Tuanjie Village Station in Chongqing, a China-Europe train (Chengdu-Chongqing) loaded with automobiles and electronic products was slowly leaving and will arrive in Duisburg, Germany, in 16 days. At this moment, 26 ambassadors from European, Asian, and African countries and regions such as Portugal, Albania, Laos, and Nigeria, including 13 ambassadors to China, are watching the train go. From March 20th to 22nd, the Ministry of Foreign Affairs organized a delegation of diplomatic envoys to China to pay a 3-day visit to Chongqing. The achievements of "Mountain City" Chongqing in advanced manufacturing, transportation and logistics have left a deep impression on the diplomatic envoys to China. "Chongqing, as an inland city, has transportation planning that connects the world, and railway, aviation, shipping, and other systems are so developed, which is very surprising." Rong Binuo, Minister Counsellor of the Portuguese Embassy in China, said that some people may have heard of this or have seen it in books, but seeing it with their own eyes still feels different. In 2022, the China Europe Railway (Chengdu Chongqing) will operate more than 5000 trains throughout the year. More than 22000 China-Europe trains have been operated in Chengdu and Chongqing, accounting for about 30% of the country's total. In addition to the westward channel to Europe, Chongqing can also be connected to Southeast Asian countries through the southward new land and sea channel in the west, China Laos railway, etc. The China Laos Railway will be completed and opened to traffic on December 3, 2021, and Chongqing is one of the first cities to run the China Laos Railway international trains. On the first day of 2023, Chongqing delivered a batch of "Chongqing made" new energy vehicles to ASEAN countries through the China Laos railway. Kuan Zan Yan Suti, the Counsellor of the Lao Embassy in China, spoke highly of the China Laos Railway and believed that it not only played a significant role in Laos' economic and social development, but also benefited other ASEAN countries. "Since the China Laos Railway was officially opened to traffic for more than a year, many data have exceeded expectations." Kuan Zan expressed his expectation that most of the products exported by ASEAN countries to China are agricultural products, but the variety of export products is expected to further increase in the future. As of December 3, 2022, the China Laos Railway has been officially opened to traffic for one year, and 24 passenger and freight stations have been opened along the whole line, with a total of 8.5 million passengers and 11.2 million tons of goods sent. The category of goods has expanded from more than 10 to more than 1200, and a striking report has been handed over. In the open channel system of Chongqing, there are also "Chongqing Manchuria Russia" international railway trains running northward, the golden waterway of the Yangtze River running eastward, and international aviation network channels. Currently, Chongqing has a four-way corridor network connecting the east, west, north, and south, covering more than 300 cities in more than 100 countries (regions). The head of the diplomatic mission to China Albanian Ambassador to China Selim Belottaya spoke highly of Chongqing's level of connectivity: "Chongqing has formed a four-way transportation pattern that connects the east, west, north, south, and provides broad space for open cooperation. Moreover, Chongqing also has many industries such as motorcycles, automobiles, and electronic products, which are quite attractive to all parties." "Before coming, I heard people say that Chongqing is a pearl of China. Now it seems that this statement is true," Belottaya said. (Liao Xinshe)
