“Grouping countries” typically refers to international or economic/political groups of nations that are often referred to by a single name or acronym (like alliances, economic blocs, or forums for cooperation).
Here are some of the most common and widely recognized ones:
G7 (Group of Seven) — Advanced economies: Canada, France, Germany, Italy, Japan, United Kingdom, United States (plus the European Union as a non-enumerated member).
G20 (Group of Twenty) — Major economies representing about 85% of global GDP: Includes G7 members plus Argentina, Australia, Brazil, China, India, Indonesia, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, and the European Union.
BRICS (expanded as BRICS+) — Emerging economies: Brazil, Russia, India, China, South Africa (original), plus newer members like Egypt, Ethiopia, Iran, Indonesia, United Arab Emirates (as of recent expansions).
ASEAN (Association of Southeast Asian Nations) — Southeast Asia: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam.
EU (European Union) — Political and economic union of (currently) 27 European countries.
AU (African Union) — Continental union of 55 African nations.
GCC (Gulf Cooperation Council) — Arab states in the Persian Gulf: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates.
NATO (North Atlantic Treaty Organization) — Military alliance primarily of North American and European countries.
Other notable ones include:
APEC (Asia-Pacific Economic Cooperation) — Forum for economies around the Pacific Rim.
OECD (Organisation for Economic Co-operation and Development) — Group of mostly high-income/developed countries.
Mercosur — South American trade bloc (e.g., Argentina, Brazil, Paraguay, Uruguay).
MINT — Emerging economies: Mexico, Indonesia, Nigeria, Turkey (sometimes used as an alternative to BRICS focus).
These groupings are used in economics, geopolitics, trade, and diplomacy. The most discussed ones globally are usually G7, G20, and BRICS due to their influence on world affairs.
If you’re referring to something more specific (e.g., geographic regions like “Nordics”, UN regional groups, or business terms like EMEA/APAC), feel free to clarify!
