In front of the South African booth at the just concluded First China International Supply Chain Promotion Expo, Anton Arenz, Chief Operating Officer of Numolux Group in South Africa, took a happy photo with several Chinese exhibitors who had agreed on cooperation intentions, and said "eggplant" in Chinese. During the Chain Expo, Arenz's company signed three agreements in the fields of health and minerals, and received more consultants than expected. This year's Chain Expo has attracted a total of 515 Chinese and foreign enterprises and institutions to participate, with approximately 130000 visitors. According to incomplete statistics, more than 200 cooperation agreements and intention agreements have been signed, involving an amount of over 150 billion yuan. Among the exhibitors and institutions, there are many exhibitors from countries jointly building the "the Belt and Road", accounting for nearly half of the total number of overseas exhibitors. Similar to Arenz, many exhibitors have achieved business expansion through the Chain Expo platform. This year marks the tenth anniversary of the initiative of jointly building the "the Belt and Road". Analysts point out that the Chain Expo has brought new opportunities for high-quality development to co built countries, becoming an important window to showcase their own advantages, helping these countries more effectively integrate into the global industrial and supply chains, and achieve industrial upgrading. Uruguay is the first MERCOSUR country to sign a memorandum of understanding with China to jointly build the "the Belt and Road" cooperation. Uruguayan President Lakale said in his opening speech that participating in the Chain Fair is a good practice for Uruguay to participate in the joint construction of the "the Belt and Road", and Uruguay is willing to further participate in such fairs. Khalid Hanafi, Secretary General of the Arab Chamber of Commerce, represented chambers of commerce in the Arab region at the Chain Expo. He told Xinhua News Agency reporters that a few months ago, when the organizers of the Chain Expo issued an invitation to participate, the Arab Chamber of Commerce Union "immediately" accepted the invitation. He expressed the hope that by participating in the Chain Expo, more people can learn about Arab countries and find opportunities for win-win cooperation. Türkiye sent a large scale delegation to participate in the Chain Fair this time. Kokhan Kurdeolu, Chairman of the China Group of Türkiye Chamber of Commerce and Industry and the Turkish China Council of the Türkiye Council on Foreign Economic Relations, said that it is very important for Türkiye's "Middle Corridor" plan to work together with the "the Belt and Road" initiative, hoping to add new energy to future bilateral cooperation.
