The G20 (or Group of Twenty) is an international body established to manage the global economy, and includes members from developing economies.This reference set examines the issues facing developing countries and studies the role that the G20 can play in light of continuing challenges and objectives to meet the UN's Sustainable Development Goals (SDG).Volume 1 sets out the state of the world economy and the intricate functions of the G20 in policy coordination and economic cooperation. It also deals with the interests and strategies of some developing country members of the G20. These chapters answer questions such as what the country expects from the G20, the strategies adopted to achieve its ends, the extent to which it sees itself as a representative of developing countries in its region and how does it seek to represent them.The G20 has also centred its efforts around helping countries achieve the UN Sustainable Development Goals (SDGs). Volume 2 concentrates on trade issues and the prospects of achieving the SDGs. In this context, it examines whether the SDGs themselves are a desirable goal in terms of what the nature of development is which underlies these goals.
