China India Mexico South Africa The Group of Five (G5) encompasses five nations which have joined together for an active role in the rapidly evolving international order.

Nowadays, the term tends to describe the next tier of nations whose economies had expanded so substantially as to be construed in the same category as the world's eight major industrialized countries.

The concept of a forum for the world's major industrialized democracies emerged following the 1973 oil crisis and subsequent global recession.

[6] In subsequent years, the group of world leaders expanded to reflect changed economic and political developments: An innovation at the Gleneagles G8 summit in 2005 was an "outreach dialogue."

[10] The G5 membership is marked by a range of attributes and factors, including (a) a shared set of normative and principled beliefs, which provide a value-based rationale for the social action of community members; (b) shared causal beliefs, which are derived from their analysis of practices leading or contributing to a central set of problems in their domain and which then serve as the basis for elucidating the multiple linkages between possible policy actions and desired outcomes; (c) shared notions of validity — that is, intersubjective, internally defined criteria for weighing and validating knowledge in the domain of their expertise; and (d) a common policy enterprise—that is, a set of common practices associated with a set of problems to which their group competence is directed.
