Timeline of Guyana/Venezuela border controversy

The Guyana/Venezuela Border Controversy started during the second half of the nineteenth century, between Venezuela and Great Britain over the location of the border between its colony of British Guiana and the Spanish-speaking country.
This continued until an Arbitral Tribunal was empanelled in 1897 to determine the borders and issued an Arbitral Award on October 3, 1899.
Following this, a Joint Commission with representatives from both countries delineated the borders in 1905. For half a century Venezuela honoured this Agreement in word and deed.
In 1931, a boundary commission made up of representatives from Great Britain, Venezuela, and Brazil agreed on the specific point on Mount Roraima where the boundaries of British Guiana, Venezuela, and Brazil met. A concrete marker was erected soon after. The matter was permanently settled.
Venezuela’s Minister of Foreign Affairs, Esteban Gil Borges in 1941 agreed that the frontier with British Guiana was well defined and was a closed issue.
However, in 1962, Venezuela, unilaterally and without any basis or evidence, announced that it regarded the Award of 1899 as null and void.
By November 1965, a meeting in London between Venezuelan and British representatives and a representative from British Guiana was held. A joint Communique stating that both sides should work to “find satisfactory solutions for a practical settlement of the controversy which has arisen as a result of the Venezuelan contention” was issued.
In February of 1966, the governments of British Guiana, Great Britain, and Venezuela, in Geneva, Switzerland signed an agreement by which a bilateral commission was appointed to seek “satisfactory solutions for the practical settlement of the controversy between Venezuela and the United Kingdom which has arisen as the result of the Venezuelan contention that the arbitral award of 1899 about the frontier between British Guiana and Venezuela is null and void.”
A mixed Commission was established out of the Geneva Agreement, however, from the beginning, Venezuela ignored the main role of the agreement under which the Commission was established to deal with Venezuela’s contention of nullity in the 1899 award.
That Mixed Commission was unable to fulfil its mandate largely because Venezuela declined to deal with the question of its contention of the nullity of the 1899 Award.
The Geneva Agreement does not state or imply that there is a territorial controversy between the countries or that there is a matter where the border between the two countries is unsettled. What it recognises and seeks to resolve is the Venezuelan contention that the Award of 1899 is null and void.
Venezuela, however, has worked feverishly over the years at turning the controversy about its contention of invalidity of the Arbitral Award into a dispute about territory.
Both Guyana and Venezuela in 1982 requested the United Nations Secretary-General to decide on a method of solution to the controversy.
The Secretary-General chose the Good Offices process in 1990.
However, in 2012, after careful consideration, the Government of Guyana had taken the decision to review its options within and consistent with the Geneva Agreement as it did not appear that Venezuela was willing to meet its obligations under the Process.
By 2014, the UN Good Offices process was declared exhausted by Guyana.
Venezuela has consistently embarked on a pattern of subversion, threats, and intimidation.
Venezuelan President Nicolas Maduro in May 2015 issued a decree, No. 1787 laying an illegal claim to almost all of Guyana’s maritime zone.
In September 2015, there was an escalation of Venezuelan military activity in eastern Venezuela near to the border with Guyana.
The Government of Guyana strongly denounced this decree calling it a flagrant violation of international law and inconsistent with the principle that all states should respect the sovereignty and territorial integrity of other states. Guyana further rejected the illegality of the decree which sought to undermine Guyana’s efforts at development through the exploitation of natural resources offshore.
In July 2015, Venezuela issued a second decree, 1859 reiterating its claim. By September that same year, Venezuelan gunboats and troops were deployed along Guyana’s borders.
On December 15, 2016, the former UN Secretary-General, His Excellency Ban Ki-Moon, informed the Presidents of Guyana and Venezuela, of his decision under Article IV (2) of the 1966 Geneva Agreement as to the means of settlement of the controversy between Guyana and Venezuela.
Secretary-General Ban informed that the Good Offices Process will continue for one final year, until December 31, 2017, with a strengthened mandate of mediation.
It was stated that if by the end of 2017, Secretary-General António Guterres concludes that significant progress has not been made toward arriving at a full agreement for the solution of the controversy, he will refer the matter to the International Court of Justice (ICJ) for juridical settlement.
In February 2017, United Nations Secretary-General Guterres named Norwegian lawyer and diplomat, Dag Nylander as Good Officer to Georgetown and Caracas.
President David Granger met with the UN Good Officer in April 2017.
On January 30, 2018, UN Secretary-General Guterres referred the matter to the ICJ for juridical settlement. (DPI)
