The term ‘Regional Comprehensive Economic Partnership’ often appears in the news in the context of the affairs of a group of countries known as

The correct answer is ASEAN (Association of Southeast Asian Nations).

The Regional Comprehensive Economic Partnership (RCEP) is one of the world's largest free trade agreements, and it is most closely associated with the group of countries known as ASEAN. Let us understand this step by step.

Step 1: What is RCEP?
RCEP is a mega free trade agreement that was signed on 15 November 2020 and came into force on 1 January 2022. It is a comprehensive trade bloc designed to reduce tariffs, open markets, and streamline trade rules among member nations across the Asia-Pacific region.

Step 2: Who are the members of RCEP?
RCEP comprises 15 countries:
— The 10 ASEAN member states: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam.
— Plus 5 ASEAN Free Trade Agreement (FTA) partner countries: Australia, China, Japan, New Zealand, and South Korea.

Step 3: Why is RCEP linked to ASEAN and not the others?
The RCEP negotiations were initiated by ASEAN at the ASEAN Summit in 2012. ASEAN served as the central negotiating hub — the deal was built around ASEAN's existing bilateral FTAs with its dialogue partners. In other words, ASEAN is the backbone and the founding force behind RCEP.

Now let us eliminate the other options to make the reasoning crystal clear:

G20 — The Group of Twenty (G20) is a forum of the world's major economies focused on international economic cooperation and financial stability. It has no direct structural connection to RCEP.
SCO — The Shanghai Cooperation Organisation (SCO) is a Eurasian political, economic, and security alliance. Its membership and mandate are entirely different from RCEP's Asia-Pacific trade focus.
SAARC — The South Asian Association for Regional Cooperation (SAARC) groups South Asian nations like India, Pakistan, Bangladesh, etc. SAARC countries are not part of RCEP, and SAARC has no role in the RCEP framework.

Step 4: The Scale and Significance of RCEP
RCEP covers approximately 30% of the world's population and nearly 30% of global GDP, making it the largest free trade agreement in history. This enormous scale is why it frequently appears in international news, and because ASEAN is its originator and central pillar, RCEP is always discussed in the context of ASEAN affairs.

Conclusion:
Because RCEP was conceived, negotiated, and anchored by ASEAN, the term "Regional Comprehensive Economic Partnership" appears in the news consistently in the context of ASEAN and its partner countries. Hence, the correct answer is unambiguously ASEAN.
