Ghana and Ivory Coast set up a body Oct. 17 to implement an international tribunal ruling on their dispute over a border running through multibillion dollar offshore oil fields, they said in a statement.

The International Tribunal for the Law of the Sea in September drew an ocean boundary that seemed to favor Ghana in a dispute with its neighbor Ivory Coast, ruling that Accra had not violated Ivorian rights in drilling for oil.

“Following last month’s ruling, the two leaders have agreed to work together and this has culminated in the setting up of a joint commission to implement the ruling,” Ghanaian foreign minister Shirley Botchwey said, reading a joint communique.

The decade-old row between the West African neighbors has put the brakes on the development of Ghana’s $6 billion offshore TEN Field, run by Tullow Oil, one of the projects in the contested area of the Atlantic.

The court ruling did not correspond with either Ghana or Ivory Coast's claim, but appeared closer to Ghana’s, and it rejected the former’s attempt to halt development.
