New York, September 28 (teleSUR-RHC)-- Venezuela and Guyana will send their respective ambassadors back to their diplomatic missions, after the neighboring country’s agreed to United Nations mediation on Sunday.

The move comes after a meeting presided over by the United Nations Secretary General Ban Ki-moon between Venezuelan President Nicolas Maduro and Guyanese counterpart David Granger, at the headquarters of the U.N. General Assembly in New York City.

Ban confirmed the U.N. will send a technical committee to Venezuela in the coming days to assess Venezuela’s claim to the Essequibo region.

The commission, which is being sent under the Geneva Agreement, will "undertake a comprehensive assessment on the circumstances of the Essequibo and then set a deadline for resolving the conflict through regular channels," Maduro added.

The disputed border between Venezuela and Guyana goes back to Venezuela's own independence struggle, which was finally won in 1821. The precise boundaries were disputed by newly independent Venezuela – which always regarded the entire area west of the Essequibo River as its border – and the United Kingdom.

A series of dubious studies and agreements culminated in a 1966 agreement between Venezuela and the Guyana, which had just achieved independence, where the two neighbors agreed to postpone settlement of the disputed territory. In May, tensions flared as Granger’s newly elected government unilaterally gave an oil concession to Exxon, leading Venezuela to call the incident a provocation.

Describing the meeting as "complex, tense and difficult," Maduro nonetheless said Venezuela has a “brotherhood” with Guyana and proposed staying in constant contact with Granger.
