Group Of 24 (G24)

The vastly misnamed Group of 77 consists of more than 130 countries, mostly small or underdeveloped nations looking to lobby for their economic interests. The G24 is a split-off organization from the G77. It represents a more managably-sized steering committee for the financial concerns of developing nations.

As with G77, the G24 doesn't put a lot emphasis on accurate names. There are actually 28 members. Also, the group lets China join, despite not being part of the official organization.
