Maritime Boundary Agreements

Maritime borders are essential both for the maintenance of peaceful borders with our neighbours and for the clear delineation of our rights and interests with regard to fisheries and living marine resources, mineral and hydrocarbon resources, freedom of navigation, maritime conscience and security and other uses of the sea. Below are the related U.S. maritime treaties and international agreements, which have been registered with the U.S. Department of State.
