AB - ABSTRACT: Political, economic and financial aspects of Colombia, with an article on the EL Cerrejon coal mining project developed by the state owned company Carbocol and Exxon. The mine will start operating this year at the rate of 200 kilotons annually to progressively attain a production of 15 million tons annually, towards 1988. Colombia's coal reserves are estimated at 17.7 billion tons.
