Costa Rica pushes Grynspan for UN chief in late bid; new chancellor named

Costa Rica made a late diplomatic push to nominate Rebeca Grynspan for the UN Secretary-General position, replacing dismissed Chancellor Manuel Tovar with Boris Marchegiani. The move signals a shift in Costa Rica's foreign policy strategy, though Grynspan's candidacy faces an uphill battle given the late timing. The change in leadership may affect regional diplomatic alignments.
