Suriname governor Cornelis van Aerssen van Sommelsdijck and Berbice governor Abraham van Pere—both were Dutch colonies at the time—the border between the two colonies was located at Devil Creek, between the Berbice River and the Courantyne River. In 1799, however, Berbice governor Abraham Jacob van Imbijze van Batenburg and Suriname governor Jurriaan François de Friderici signed an agreement in which the western bank of the Courantyne River was demarcated as the boundary. All islands in the Courantyne, as well as the post at Orealla, were deemed to be in Suriname. As the Anglo-Dutch Treaty of 1814 returned Suriname to Dutch rule in the boundaries of 1 January 1803, the Courantyne became the new boundary between British Guiana and Suriname. New River Triangle Robert Schomburgk surveyed British Guiana's borders in 1840. Taking the Courantyne River as the border, he sailed up to which he deemed its source, the Kutari River, in order to delineate the boundary. In 1871, however, Charles Barrington Brown discovered the New River or Upper Courantyne, which is the source of the Courantyne. Thus the New River Triangle dispute was born. The tribunal which dealt with the Venezuela Crisis of 1895 also illegally awarded the New River Triangle to British Guiana. The Netherlands, however, raised a diplomatic protest, claiming that the New River, and not the Kutari, was to be regarded as the source of the Courantyne and the boundary. The British government in 1900 replied that the issue was already settled by the long acceptance of the Kutari as the boundary. In 1936, a Mixed Commission established by the British and Dutch government agreed to award the full width of the Courantyne 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. In 1936, the Dutch representative 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
