The UN Commission on the Limits of the Continental Shelf (CLCS) has approved and endorsed a joint claim from the Federated States of Micronesia, Papua New Guinea, and the Solomon Islands. The joint claim over 600,000 square kilometers of additional seabed, on what is known as the Ontong Java Plateau, was lodged in 2009. More information is available here and here.
