In 2010, the governments of Grenada, on the one hand, and Trinidad and Tobago entered into discussions which eventually led to the adoption of a maritime boundary between Grenada and Trinidad and Tobago. This boundary was demarcated by The Joint Boundary Commission of Grenada and Trinidad siting in the Republic of Trinidad and Tobago's capital, Port of Spain.
In 2011, Grenada and Trinidad and Tobago have begun a series of discussions on possible areas of co-operation, and collaboration in the Energy Sector and expressly with respect to Grenada's development of its own offshore oil and gas sector.
In September 2012, the Grenadian Government and also the Government of the Republic of Trinidad and Tobago has signed a cooperation agreement for energy development. This agreement will include the joint exploration and exploitation of hydrocarbons in the maritime areas in Trinidad and Tobago and Grenada and also have technical support and skills in the oil and gas projects and activities.
