The BBNJ Agreement, also known as the High Seas Treaty, entered into force this January after decades of negotiations. It provides a framework for protecting marine life in international waters, including the creation of marine protected areas – an essential step toward the global goal of protecting 30% of the planet by 2030. As countries consider where to locate the treaty's secretariat, the UN Secretary-General's Special Envoy for the Ocean, Peter Thomson, spoke with CGTN's Dong Xue about Xiamen's bid and China's role in putting the agreement into action.
