On August 4, 2014, the International Criminal Court (ICC) and the Parliament of MERCOSUR concluded an Exchange of Letters [3] for the establishment of a Framework Cooperation Arrangement between the two entities.  According to the press release [4], “the two organisations agreed to develop their mutual cooperation on matters of common interest” and foresee the Arrangement as helping to “intensify the involvement of MERCOSUR and its Member States in the international criminal justice system.”  In his remarks [5] at the signing ceremony, ICC President Sang-Hyun Song noted that “every one of the 12 MERCOSUR Member States is a State Party to the Rome Statute.”
