Taoiseach Enda Kenny has said Ireland is in a position to push the issue of the prevention of hunger to the top of the international agenda.
Mr Kenny was speaking before attending a conference at Downing Street to highlight the problem of child malnutrition.
British Prime Minster David Cameron is using the Olympics to invite international leaders and agencies to consider new approaches to child malnutrition.
He wants to secure commitments from countries and multinational companies to help prevent 25m children under five suffering stunted growth by the time of the next Olympics in 2016 in Brazil.
Mr Kenny said Ireland will use its EU Presidency next year, in conjunction with Britain's Presidency of the G8, to push the issue to the top of the international agenda.
