The 139th edition of the China Import and Export Fair, also known as the Canton Fair, opened on Wednesday in Guangzhou City of south China's Guangdong Province, with its exhibition space, number of booths and participating enterprises all reaching record highs.

The fair covers 1.55 million square meters and features 75,700 booths and more than 32,000 participating enterprises, with around 3,900 first-time exhibitors.

The number of exhibition zones has increased to 179, including nine new sections covering smart wearables, display technologies, consumer drones, modular houses and garden facilities.

The fair, taking place from April 15 to May 5, features three distinct phases, each focusing on different product categories themed on "advanced manufacturing", "quality home life" and "better life".

Established in 1957, the Canton Fair is held twice a year in Guangzhou. It is the longest-running of several comprehensive international trade events in China, and has been hailed as the barometer of China's foreign trade.
