China Marine Economy Expo (CMEE) 2026Dates, Registration & Visitor Guide

What is China Marine Economy Expo (CMEE)?

The China Marine Economy Expo (海博会) is China's national showcase for the "blue economy": offshore energy, shipbuilding and shipping, ocean monitoring, underwater robotics, marine electronics, marine biomedicine and coastal tourism. It takes place every October at Shenzhen World in Bao'an and ties in with the city's push to become a "global marine centre city"; the Shenzhen government held an official press conference to launch the 2025 edition. The show is operated by Canton Fair Advertising Co. with two partner companies. Its organizers describe it as China's only national-level marine economy exhibition and the country's top ocean show.

The 2026 edition is organised around eight zones: deep-sea energy development, marine electronics, green shipping and low-carbon logistics, ocean monitoring and disaster warning, modern marine services and coastal tourism, low-altitude (drone) applications at sea, marine biomedicine, and marine ecology. There are also special areas for international exhibitors, APEC ocean cooperation and ocean start-ups. At the 2025 edition, when more than 300 companies exhibited over roughly 40,000 m², the floor had big state groups (China Merchants, China Communications Construction, Shenzhen Port, CNOOC, CIMC, Shenzhen Energy, Ansteel), telecoms operators China Mobile and China Unicom, and tech companies including Huawei and Inspur alongside smaller ocean-tech firms such as Zhilan (underwater acoustic communication and positioning). Companies already announced for 2026 include the CAS Xi'an Institute of Optics and Precision Mechanics (deep-sea cameras and underwater optical communication), Hollysys (offshore platform control systems), Mairun (AI vision for smart shipping) and Haiying (sonar and ADCP instruments, part of the CSSC group).

The forums are a large part of the draw. The Marine Centre City Forum has run alongside the expo since 2019. For 2026 it has France as guest of honour and Hainan as guest province, with sessions on shipping and ports, ocean renewables, blue finance, APEC cooperation and AI in ocean industries. In 2025 the programme also included an APEC ocean seminar, and the concurrent Shenzhen International Ocean Week added public ship open days and ocean science activities.

For foreign visitors it is a useful single stop to meet China's port, shipping, offshore-energy and ocean-instrument players, and to scout Shenzhen and Pearl River Delta suppliers of marine electronics, drones and underwater robots. In 2025 entry was free for visitors who registered online. The organizers have promoted the 2026 show abroad at SMM Hamburg and in Singapore, so expect some international delegations.
