Uruguay's President Yamandú Orsi on Tuesday assumed the pro tempore presidency of Mercosur and set as a priority of his term to "keep modernizing" the bloc and consolidate its trade opening, following the provisional entry into force of the agreement with the European Union. "We want a more modern, more dynamic Mercosur, more open to the world, but above all a Mercosur that produces concrete results for its citizens," he said as he received the rotating presidency from host Santiago Peña of Paraguay, at the 68th summit of heads of state held in Luque.
