NAIROBI, Kenya (AP) — African and Commonwealth nations called Tuesday for a swift implementation of a landmark treaty protecting the high seas, warning that despite record commitments to marine conservation, much of the world’s ocean protection still exists only on paper.The call to action was issued at the 11th Our Ocean Conference in Mombasa, Kenya, the first time an African nation has hosted the major annual event, which focuses on addressing critical ocean issues, including climate change, biodiversity and pollution. Hundreds of delegates from Africa, the United States, the European Union, and climate-vulnerable Caribbean and Pacific island nations are taking part in the conference, where leaders have sought to position Africa as a driving force in global ocean governance. Former U.S. Secretary of State John Kerry said in his opening remarks at the Commonwealth Ocean Ministers’ Roundtable that the High Seas Treaty, which came into effect in January 2026 after ratification by 60 countries, marked a historic turning point by creating, for the first time, a legal mechanism to establish protected areas in international waters.

But he warned that progress remained too slow.
