The 133rd Canton Fair enters its third phase today in south China's Guangzhou. This year's exhibition features three new categories: industrial automation and intelligent manufacturing, new energy and smart vehicles, and maternal and baby products. It also added new zones for intelligent life, the silver economy, detection reagents, and pandemic protective equipment. Li Yong, chief researcher at D&C Thinktank in Beijing, says that those new additions show China's upgraded supply structure is adapting to new global demands.
