Seeking to give an international angle to his presidential bid, City Mayor Horacio Rodríguez Larreta headed out in midweek for an official tour to Washington where he will be meeting up with White House officials, senators, businessmen, think tanks and Georgetown University students. Sustainable food production and climate change will reportedly top his agenda while he will also be received by State Department authorities for a dialogue on democracy in the region, cooperation against terrorism and the opportunities offered by Argentina in food, energy and lithium.
