In 1936, a Mixed Commission established by the British and Dutch government agreed to award the full width of the Corentyne River to Suriname, as per the 1799 agreement. The territorial sea boundary was deemed to prolongate 10° from Point No. 61, from the shore. The New River Triangle, however, was completely awarded to Guyana. The treaty putting this agreement into law was never ratified, because of the outbreak of World War II. The Dutch representative Conrad Carel Käyser signed an agreement with British and Brazilian representatives, placing the tri-point junction near the source of the Kutari River. Desiring to put the border issue to a closure before British Guiana would gain independence, the British government restarted negotiations in 1961. The British position asserted "Dutch sovereignty over the Corentyne River, a 10° line dividing the territorial sea, and British control over the New River Triangle." The Netherlands replied with a formal claim to the New River Triangle, but with an additional thalweg boundary in the Corentyne River (the latter position has never been repeated by any Surinamese government). No agreements were made and Guyana became independent with its borders unresolved.
