Frequently Asked Questions
How many specialized agencies does the UN have?
The United Nations has 15 specialized agencies, including WHO, UNESCO, ILO, FAO, IMF, World Bank, and others. These are autonomous international organizations linked to the UN through special agreements. They have their own governing bodies, budgets, and headquarters — distinct from UN programmes and funds.
What is the difference between IMF and World Bank?
The IMF focuses on monetary stability, exchange rate management, and providing short-term financial assistance during balance of payments crises. The World Bank focuses on long-term economic development, poverty reduction, and infrastructure financing through loans and grants to developing countries. Both were established at Bretton Woods in 1944.
Why isn't India a permanent member of the UN Security Council?
India has been advocating for UNSC reform and permanent membership as part of the G4 group. The current permanent members (P5) were decided in 1945 based on post-World War II power dynamics. Expanding the council requires amending the UN Charter, which needs approval from two-thirds of the General Assembly and all five current permanent members.
What is India's role in BRICS?
India is a founding member of BRICS alongside Brazil, Russia, China, and South Africa. India actively participates in BRICS summits, the New Development Bank, the Contingent Reserve Arrangement, and various cooperation mechanisms in areas like counter-terrorism, digital economy, agriculture, and cultural exchange.
Which international organizations have their headquarters in India?
No major global international organization has its permanent headquarters in India. However, India hosts regional offices of several organizations — the WHO South-East Asia Regional Office in New Delhi, the International Solar Alliance (ISA) headquarters in Gurugram, and the Coalition for Disaster Resilient Infrastructure (CDRI) secretariat in New Delhi.
