Being the biggest manufacturing hub in the world, China plays a central role in global supply chains and global value chains in the areas of smart manufacturing, digital technologies, and clean energy, said Rafael Suchan, CEO of Vastalta Circular Technology, in an interview with CGTN during the ongoing China International Supply Chain Expo 2024. He also noted the participation in this event has also been facilitated thanks to China's relaxed visa policies for dozens of countries which makes it much easier now for international travelers to come to China.
