Shanghai rolls out the red carpet for the 5th China International Import Expo this weekend. The expo has drawn more than 280 exhibitors, including the world's top 500 and other industry leading companies. Could CIIE 2022 build on the growth momentum? Over the years, how much weight does the CIIE shoulder? Li Yong, the deputy chairman of the Expert Committee of the China Association of International Trade, says people can expect a lot from this expo as a champion of China's efforts toward high-quality opening-up.
