That same day, the Andean Pact foreign ministers meeting in San José de Costa Rica publicly rejected the Urcuyo maneuver: "We urge Urcuyo to abide by the obligation to transfer power, the only reason he occupies it. For his permanence in it will only contribute to the current contest acquiring new and more violent military dimensions. "
