evidence: The Tigri region has been in dispute since 1840. This territory is delimited by the Boven-Courantyne and the Coeroeni and Kutari rivers. Guyana refers to it as the New River Triangle. [...] Since 1969, the Tigri area has been controlled by Guyana. In 1971, both governments agreed that they would continue talks on the border issue and would withdraw their military forces from the disputed triangle. However, Guyana has never acceded to this agreement. [...] There are similarities between the Tigri area and the Essequibo, since both disputes began at the same time and have the same protagonist, Robert Hermann Shomburgk. Robert Hermann Shomburgk drew the Shomburgk lines which took territory away from Venezuela. Added to this is the fact that the Court of Paris acted in both cases (Paris arbitration award, 1899, not recognized by Venezuela).
