Companies and institutions from the United States have ranked first among foreign exhibitors at the China International Supply Chain Expo for four consecutive years, from the inaugural event to this year's fourth edition, the China Council for the Promotion of International Trade said on Friday.

The US business community's active participation, experts said, underscores the enduring pull of the Chinese market and the deep integration of US supply chains with China's manufacturing ecosystem.

The event is set to run from June 22 to 26 in Beijing, with 676 leading Chinese and foreign companies confirmed to exhibit, Li Xingqian, vice-chairman of the council, told a news conference.

According to Li, participating companies hail from 85 countries, regions and international organizations. Foreign exhibitors account for 36.5 percent of the total, while Fortune Global 500 companies and industry leaders make up over 65 percent.

This year's expo will for the first time feature a dedicated artificial intelligence zone, developed in collaboration with leading global semiconductor companies and designed to showcase the full AI ecosystem, from data collection and computing power, to algorithms and real-world applications, Li said.
