Angola said on Thursday it would leave OPEC over a disagreement on production quotas following the oil cartel's decision last month to further slash output next year.
Mineral Resources and Petroleum minister Diamantino Azevedo said that the decision was not taken lightly, but OPEC membership no longer served the African country's interests.
"We feel that at this moment Angola gains nothing by remaining in the organization and, in defence of its interests, it decided to leave," the presidency quoted Azevedo as saying in a statement.
