NEW YORK: The UN Security Council on Monday expressed its concern over the smouldering border dispute between Venezuela and Guyana, reported German news agency (dpa).

Council members called on the conflicting parties to exercise the greatest possible restraint in their dispute over the Essequibo region in South America, according to a spokesman.

The most powerful body of the United Nations called for differences to be resolved by peaceful means and for all obligations under international law and the United Nations Charter to be honoured.

Venezuela’s President Nicolás Maduro recently passed a law declaring the border region of Essequibo, which belongs to Guyana, a Venezuelan federal state.

According to official figures, a large majority of Venezuelans voted in favour of annexing the region, in a controversial referendum in December.

Venezuela has long laid claim to the resource-rich territory, which covers around two thirds of the neighbouring country.

The current borders were established in 1899 in an arbitration ruling by a tribunal in Paris, which was initiated by the United States and Britain.

Venezuela refers to an agreement with the United Kingdom from 1966, a few months before the then colony of British Guiana became independent. This provided for a negotiated solution to the dispute.

Immense oil reserves were discovered off Guyana’s coast in 2015. This has now brought the English-speaking country – previously one of the poorest in South America – the world’s highest economic growth. - Bernama, dpa
