The most professionalized exhibition of Argentine agroindustrial sector witnessed a historic landmark, no doubt testimonial. The presence of the president of the nation for the first time in Expoagro staged changing agricultural policy. The previous government had decided to interventionism and control of exports of agricultural products. Instead, Macri Administration is implementing and stimulating measures such as the reduction of withholding tax, currency devaluation and removes obstacles to sell more across borders. Obama's visit to the country is another opportunity to reopen or improve access to the US market for some of its productions.
