The Commission acknowledges that improvement of public sector effectiveness can be achieved through, inter alia, dialogue, partnership and cooperation at all levels. The Commission encourages Governments to strengthen the exchanges of experience and methods of effective delivery of public services. The United Nations system and international financial, trade and economic institutions and bilateral donors are invited to play an important role, through an integrated and coherent approach, in assisting Governments, in particular those of developing countries, least developed countries and countries with economies in transition, in this endeavour, specifically in exchanging and disseminating good practices and capacitybuilding activities aimed at improving public sector effectiveness.
