Chile's Defense Minister Fernando Barros Tocornal said his country's support for Argentina's sovereignty claim over the Falklands (the South Atlantic archipelago Argentina calls the Malvinas, administered by Britain since 1833) does not restrict trade between the southern Magallanes region and the islands. Speaking to a Punta Arenas radio station, he said oil and mining exploration would be the most contentious issue and that Chile's Mercosur and Unasur commitments are political rather than legally binding. The remarks do not change Chile's formal position, reaffirmed in a September 3 declaration with Argentina, but they come as a Falklands development agency and a Chilean shipping firm plan a Punta Arenas–Stanley sea link, with a first voyage reportedly set for November.
