No 4 Why so many developing countries?

Laos, Chad, Senegal, Thailand, Kazakhstan and Egypt are developing countries without G20 membership, but their participation will enable the G20 Hangzhou summit to become one attended by the most number of developing countries in G20 history.

Ruan Zongze, executive deputy president of the China Institute of International Studies, said the G20 is set to address development issues. While developing countries are less represented in some international institutions, the Group of 20, which acts as a major forum for global economic governance, should allow developing countries to have a bigger say.
