 On some maps, the western Essequibo region is called the "Zone in Reclamation".In 1983 the deadline of the Port of Spain Protocol expired, and the Venezuelan President Luis Herrera Campins decided not to extend it anymore and resume the effective claim over the territory.Since then, the contacts between Venezuela and Guyana within the provisions of the Treaty of Geneva are under the recommendations of a UN Secretary General's representative, who can be changed from time to time under agreement by both parties.
