UK weighs blocking Argentina from OECD, CPTPP over Falklands oil dispute

The UK is considering blocking Argentina's accession to the OECD and a Pacific trade pact in response to Argentine measures against companies tied to the Sea Lion oil project. Chile is meanwhile developing a maritime route to supply the islands commercially, adding a new dimension to the sovereignty dispute. The move signals a hardening of UK posture, though the specific trade agreement and OECD process remain uncertain.
