ADEX: Background and Global Credentials

ADEX was initiated by UnderWater360 and has been running for more than 30 years. It has grown into a respected international platform integrating marine-industry upstream and downstream, island tourism, technology and equipment, environmental protection, outdoor sports and diving, marine digital rights, arts education, and the renowned global “mermaid water-dance” shows.

For Hainan, hosting ADEX marks a significant milestone in the island’s evolution as a hub for global marine-tourism and dive-industry business. The event’s scale, international scope and focus on sustainability align with Hainan’s positioning as a tropical-marine destination with growing infrastructure and ambition.
