India's Neighbours — A Deep Dive
Free study material · concepts, shortcuts & solved questions
This is the single most exam-relevant cluster in the entire book for an Indian aspirant — India shares a land border with seven countries (Pakistan, China, Nepal, Bhutan, Bangladesh, Myanmar, and, via a narrow Pakistan-occupied-Kashmir strip, a contested proximity to Afghanistan) and a maritime boundary with two more (Sri Lanka and the Maldives). Walk this ring clockwise from the north-west every time you revise it.
| Neighbour | Capital | Currency | Indian border states | Key relations context |
|---|---|---|---|---|
| Pakistan | Islamabad | Pakistani Rupee | Jammu & Kashmir, Ladakh, Punjab, Rajasthan, Gujarat | Partitioned from British India in 1947; Line of Control divides Jammu & Kashmir; longest and most militarised of India's land borders |
| China | Beijing | Renminbi (Yuan) | Jammu & Kashmir/Ladakh, Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh | Border known as the Line of Actual Control (LAC), not a formally demarcated international boundary; 1962 war and 2020 Galwan clash are the two most-tested flashpoints |
| Nepal | Kathmandu | Nepalese Rupee (pegged to INR) | Uttarakhand, Uttar Pradesh, Bihar, West Bengal, Sikkim | Open border with free movement under the 1950 Treaty of Peace and Friendship; landlocked, depends heavily on Indian transit routes |
| Bhutan | Thimphu | Ngultrum (pegged 1:1 to INR) | Sikkim, West Bengal, Assam, Arunachal Pradesh | Close strategic partnership; India assists Bhutan's foreign and defence policy coordination without a colonial-style dependency; Doklam (2017) standoff involved Bhutan, India, and China together |
| Bangladesh | Dhaka | Taka | West Bengal, Assam, Meghalaya, Tripura, Mizoram | Created in 1971 after the Bangladesh Liberation War, with Indian military support; shares the world's longest river-delta border and the Teesta water-sharing dispute |
| Myanmar | Naypyidaw | Kyat | Arunachal Pradesh, Nagaland, Manipur, Mizoram | India's only ASEAN-member land neighbour; the border region is central to India's "Act East" policy and to insurgency/refugee-flow concerns |
| Sri Lanka (maritime) | Sri Jayawardenepura Kotte / Colombo | Sri Lankan Rupee | No land border — separated by the Palk Strait from Tamil Nadu | Fishermen's rights disputes across the Palk Strait; Tamil ethnic-conflict history colours bilateral relations |
| Maldives (maritime) | Malé | Maldivian Rufiyaa | No land border — nearest to Lakshadweep/Kerala coast | Strategically important Indian Ocean partner; a member of SAARC alongside India |
A note on Afghanistan: India does not share a direct land border with Afghanistan under international law, since the intervening territory (the Wakhan Corridor's southern approach and the wider region) runs through Pakistan-administered territory; India nonetheless treats Afghanistan as a close neighbour for policy purposes and both remain SAARC members together.
A few relationship-specific details are worth attaching to each neighbour beyond the bare capital-currency-border facts, since exam questions increasingly blend static geography with a light current-affairs layer. India and Bhutan's relationship is unusually close among India's neighbours — Bhutan coordinates its foreign policy closely with India under a 1949 treaty (revised in 2007 to give Bhutan fuller sovereign discretion), and the 2017 Doklam standoff was a genuine three-country event: Chinese road-building in territory claimed by Bhutan triggered an Indian military response on Bhutan's behalf, illustrating exactly why Bhutan's neighbour-relations can't be studied in isolation from India-China ties. Nepal and Bhutan both peg their currencies to the Indian rupee (Nepal's rupee and Bhutan's ngultrum both trade 1:1 or near-1:1 with the INR), a monetary detail that is itself evidence of how tightly both economies are integrated with India's. Bangladesh's Teesta river water-sharing dispute remains one of the longest-running unresolved bilateral issues between the two countries, alongside cooperation on trade, connectivity, and counter-terrorism that has generally strengthened since 1971. Myanmar's border with India runs through some of the most historically insurgency-affected Indian states (Nagaland, Manipur, Mizoram), and India's engagement with Myanmar sits at the geographic core of its "Act East" policy, aimed at deepening trade and connectivity links with ASEAN.
Practice Recall: Name the treaty year (and its 2007 revision) that governs India-Bhutan foreign-policy coordination, the river at the centre of the India-Bangladesh water-sharing dispute, and the Indian foreign-policy framework under which Myanmar ties are usually discussed.
Memory hook — "PC-NB-BM, plus two islands": Pakistan, China, Nepal, Bhutan, Bangladesh, Myanmar — six land neighbours in one line, clockwise from the northwest — plus Sri Lanka and the Maldives as the two maritime-only neighbours across water.
Practice Recall: List all seven Indian states bordering China, then name the one country that is both a SAARC member and does not share a land border with India, and the one ASEAN member that does share a land border with India.
