Revision summary
Diplomacy is a Union power; influence is political. Tamil Nadu–Sri Lanka and West Bengal–Bangladesh are classic pairs. North-eastern States shape the Myanmar and refugee files. Kerala’s Gulf link is diaspora diplomacy from below. Coalitions raise State leverage; a strong Centre can still override.
Model answer
Introduction
The Constitution puts foreign affairs in the Union List. In practice, border States, diaspora States, and coalition politics push New Delhi. Influence is partisan and geographic. It is not a second External Affairs Ministry in every capital.
Body
Formal design
- Treaty-making, war, and diplomacy are Union subjects. The Centre can still be politically unable to ignore a State.
- Inter-State Council and occasional chief-minister visits are weak formal channels. The real channel is party and protest.
Border and ethnic files
- Tamil Nadu shapes Sri Lanka policy through the Tamil question and fisheries.
- West Bengal affects Bangladesh on Teesta, migration, and border haats.
- Punjab and Jammu and Kashmir sit on the Pakistan and people-to-people file.
- North-eastern States shape Myanmar policy, the Free Movement Regime, and refugee shelter, as in Mizoram’s Chin inflows.
Economic and diaspora States
- Kerala and the Gulf: remittances and evacuation diplomacy.
- Gujarat and Maharashtra: ports, investment, and some neighbourhood commerce.
- IT States lobby on visas to the United States and the UK.
Coalition and federal politics
- When the Centre needs State parties, a regional veto can delay a treaty or a water-sharing signature.
- Para-diplomacy: States open trade offices and court NRIs. They cannot recognise States or send ambassadors.
Limits
- Doklam and Galwan were Union military files. States did not set the LAC.
- A determined Centre can override, at a political cost.

Conclusion
Constituent States influence Indian foreign policy where identity, water, migration, and diaspora meet the border or the Gulf. The Union still owns the legal core. Federal politics is the transmission belt, especially under coalitions.

-
Can a State sign a treaty?
No. It can lobby, delay implementation, and run trade promotion. The President and Union government remain the treaty face.
-
Is this unique to India?
Federal systems generally show para-diplomacy. India’s ethnic borders make it unusually sharp in the neighbourhood.

India continues to invoke its time-tested policy of strategic autonomy vis-à-vis both the United States of America and Russia by rejecting US' offer of mediation on Kashmir issue and by refusing to criticize Russia in its ongoing war against Ukraine. Comment
Indian Foreign Policy
Strategic autonomy means India will not outsource core security choices to a patron. Kashmir is treated as bilateral; U.S. mediation offers are refused, especially after terror shocks such as Pahalgam. On Ukraine, India avoids Western condemnation blocs while buying oil and keeping Russian platforms, without endorsing conquest. The two refusals share a doctrine but not the same moral file. This is NonAlignment 2.0 practice: partners, not instructors.

Indian Foreign Policy
FOIP for India is an open maritime order, not a Chinese lake or a U.S. private canal. Core partners: Japan, the United States, Australia, France and ASEAN; Quad is the sharpest minilateral. Connectivity — SAGAR, IPOI, IMEC, Chabahar, INSTC, digital public goods — is the other half of ‘assurance’. The strategy is sound; neighbourhood leakage and thin shipyard capacity make it incomplete. A portfolio of partners, not one ally, is the actual policy.
Q8(a) · UPSC Mains 2024 · PSIR GS 2 · 20 marks
Critically examine the continuity and change in India's Palestine policy in the wake of the ongoing Israel-Hamas War.
Indian Foreign Policy
Baseline India policy was anti-colonial support for Palestine, two states, and UN voting with the South. From the 1990s–2010s India de-hyphenated and built defence and technology ties with Israel. After October 2023 India condemned Hamas’s terror quickly and kept humanitarian and two-state language as the war widened. Continuity is the diplomatic formula; change is partner hierarchy and the terror frame. Critical need: keep both sentences, because dropping either one breaks either the South or India’s own terrorism diplomacy.
