Moreno was included in the Bolivia squad for the 2015 Copa América in Chile. On 15 June, he scored the decisive goal in the team's second group match – a 3–2 defeat of Ecuador – to give "La Verde" its first win at the Copa América since the 1997 tournament. He was Bolivia's top scorer at the tournament with two goals, also being the only Bolivian player to score in the knockout stage as the side lost 1–3 to Peru in the quarter-finals. Moreno announced his retirement from the national squad on 15 September 2015 together with then captain Ronald Raldes, claiming divergences with head coach Julio César Baldivieso.
