China's Bold Bid for High Seas Treaty Control

In a significant move for global environmental governance, China has proposed the city of Xiamen to host the secretariat of the new high seas treaty. This surprise bid, communicated to the UN Secretary-General, indicates Beijing's ambition to influence international environmental policy. The treaty itself officially becomes effective on January 18, 2026, after years of negotiation and a ratification process completed in September by 60 countries.

The treaty's primary objective is to safeguard biodiverse regions within global waters, extending protection beyond national exclusive economic zones. These ocean areas are crucial for producing half of the planet's oxygen and are vital in the fight against climate change. Establishing a decision-making body under this treaty will necessitate coordination with numerous existing regional and global organizations already overseeing various marine aspects.

China's proposal comes at a time when global cooperation frameworks are being re-evaluated, following the US announcement of withdrawal from several international agreements. The selection of the secretariat's host country is scheduled for later this year, with Belgium and Chile previously being the primary candidates vying for the role.
