Promoting better policies for better lives in emerging and developing economies is an integral part of the OECD’s mission. It is also an essential contribution to the prosperity and stability of its members. Most OECD departments and special bodies therefore lend their expertise to supporting policy making in partner countries, but only three of them specialise in international development: the OECD Development Co-operation Directorate, the OECD Development Centre, and the Sahel and West Africa Club. The OECD Development cluster works in close co-operation with OECD sectoral committees and directorates. It leverages the Organisation’s assets to support better policies globally, and advance the 2030 Agenda for Sustainable Development. The cluster’s combined networks and expertise ensures that this support is directly informed by partner countries’ governments and stakeholders, adapted to their specific challenges and opportunities, and implemented with regional partners.
