evidence: A contrary position was asserted by the Government of the Netherlands in 1961-1962 negotiations, this time giving British Guiana a 33Âº (34Âº was also considered) maritime extension, but with the Dutch retaining control of the New River Triangle. The Corentyne (or "Courantyne") River, the large dividing river between the parties, has, in its entirety, been under consistent Dutch and later Suriname control. The islands in the river are deemed Suriname territory, and local authorities have reportedly prevented Guyanese fishing on the river. Normally a thalweg, or middle point of a navigable channel in a river, forms the boundary between two adjacent countries. However, through inheritance of title, Suriname contends that the land boundary terminus lies on the Guyana bank of the Courantyne River. Today, Suriname contends that the earlier 10Âº prolongation extends throughout the Continental Shelf, Territorial Sea and Exclusive Economic Zone and wishes to continue to link the resolution of the New River Triangle to the maritime issues. Guyana argues that a 34Âº prolongation is applicable. The long-standing Guyanese concessions within this "triangle of overlap" signify historic title, as Suriname has effectively relied on their presence since their initial appearance over fifty years ago. The decision to invoke Annex VII of the Law of the Sea Convention is the first time that either country has been willing to arbitrate only one section of the three disputed territories. All previous attempts to settle the dispute intrinsically linked inland territory and maritime zones.
