Venezuelan President Nicolas Maduro has vowed to bar US petroleum giant ExxonMobil from the waters off the oil-rich region of Essequibo, which Caracas claims from Guyana as its own.
The head of ExxonMobil in Guyana, Alistair Routledge, revealed plans this month for two exploratory wells off the coast of Essequibo, saying the company wanted to develop new sites in an area where there was no existing infrastructure.
