Connectivity

1. Meaning and diplomatic significance

Connectivity comprises physical infrastructure and the rules, institutions and services that make cross-border movement possible. Hard connectivity includes highways, rail tracks, ports, transmission lines and optical-fibre networks. Soft connectivity includes customs procedures, transport permits, interoperable payment systems, safety standards and mutual recognition of documents. A completed bridge produces limited benefits if restrictive transit rules prevent vehicles from crossing it.

For India, connectivity operationalises Neighbourhood First by creating tangible benefits for neighbouring populations. It also supports Act East by connecting eastern and northeastern India with Southeast Asia. Bangladesh, Nepal and Bhutan are especially important to subregional integration, while Myanmar provides the land bridge towards ASEAN. Maritime links with Sri Lanka and Maldives extend neighbourhood diplomacy into the Indian Ocean.

Its strategic significance lies in reducing economic isolation and increasing mutual stakes in stable relations. However, interdependence is not an automatic guarantee of political alignment. Smaller neighbours seek diversified partnerships and remain sensitive to sovereignty and asymmetry. India therefore gains more durable influence through reliable, locally valued public goods than through demands for exclusive strategic loyalty.

• Economic objective: reduce logistics costs, expand markets and facilitate regional production networks.
• Developmental objective: connect border districts and India’s Northeast to neighbouring economic centres.
• Diplomatic objective: build trust through visible, mutually beneficial cooperation.

2. Land transport and border infrastructure

India–Bangladesh connectivity illustrates the recovery of transport networks disrupted by Partition. Railway links such as Haldibari–Chilahati have been restored, while the Akhaura–Agartala cross-border rail link was inaugurated in November 2023. Such projects can shorten routes between Tripura and Bangladesh’s transport system, but inauguration must be distinguished from sustained commercial operation. Political conditions, customs arrangements and service availability determine actual utilisation.

With Nepal, the Jayanagar–Kurtha passenger rail service commenced in April 2022 and was subsequently extended to Bijalpura. Cross-border rail and road projects support trade, tourism and the movement of people within the distinctive India–Nepal open-border relationship. Integrated Check Posts combine customs, immigration and related facilities; the Land Ports Authority of India, constituted under a 2010 law, develops and manages designated land ports.

The BBIN Motor Vehicles Agreement seeks to facilitate passenger, personal and cargo vehicle movement among Bangladesh, Bhutan, India and Nepal. Bhutan’s non-ratification, influenced partly by environmental concerns, demonstrates the importance of domestic consent. Implementation requires agreed protocols, insurance arrangements and customs procedures; the agreement should not be treated as a fully operational four-country transport regime.

The India–Myanmar–Thailand Trilateral Highway would extend connectivity towards Southeast Asia. Yet difficult terrain, incomplete works and Myanmar’s conflict constrain its potential. This reveals a recurring diplomatic lesson: infrastructure construction and the political conditions needed for safe transit must advance together.

3. Waterways, maritime links and multimodal corridors

India and Bangladesh possess a natural advantage in their interconnected river systems. The 1972 Protocol on Inland Water Transit and Trade enables movement along agreed routes and through designated ports of call. Protocol routes can connect mainland India with the Northeast through Bangladesh. Operational reliability nevertheless depends on navigable depth, dredging, terminal facilities, seasonal conditions and efficient border clearance.

Access arrangements for Bangladesh’s Chattogram and Mongla ports offer additional options for northeastern India. Their significance is not merely shorter distance: predictable access can encourage warehousing, processing and cross-border value chains. Bangladesh benefits through port services, transit-related activity and stronger demand for its logistics infrastructure. Benefits must be assessed against total transport costs rather than distance alone.

The Kaladan Multi-Modal Transit Transport Project combines a sea route from Kolkata to Sittwe, inland water transport towards Paletwa, and a road connection towards Mizoram. Sittwe port was inaugurated in May 2023. However, incomplete connectivity and insecurity in Myanmar have prevented the project from functioning as a seamless, dependable corridor. Kaladan and Bangladesh routes offer alternatives to the existing dependence on the Siliguri Corridor; they do not eliminate its strategic importance.

Across the maritime neighbourhood, the Nagapattinam–Kankesanthurai ferry link, launched in October 2023, illustrates the potential of affordable passenger connectivity with Sri Lanka. India-supported bridge infrastructure in Maldives similarly links development cooperation with everyday mobility. Commercial viability, maintenance capacity and environmental safeguards remain essential.

4. Energy and digital connectivity

Electricity trade is an increasingly important form of regional integration. India and Bhutan have long cooperated in hydropower development and electricity exchange. Nepal’s growing exports to India create opportunities to monetise hydropower, while Bangladesh seeks additional sources of electricity. Seasonal generation patterns and differences in demand can support mutually beneficial exchange, provided transmission capacity and commercial arrangements are adequate.

India’s Ministry of Power issued guidelines for cross-border electricity trade in 2018, followed by the Central Electricity Regulatory Commission’s cross-border trade regulations in 2019. These frameworks support electricity exchange while retaining regulatory and security scrutiny. Nepal’s 40 MW export to Bangladesh through India in November 2024 demonstrated that connectivity can move beyond bilateral projects towards trilateral cooperation.

The Motihari–Amlekhgunj petroleum-products pipeline, inaugurated in September 2019, provides a different energy-connectivity model. It reduces reliance on road tankers for supplies to Nepal and can improve delivery reliability. Pipelines and power lines, however, create long-term dependence on agreed pricing, technical standards and dispute-management mechanisms.

Digital connectivity includes fibre links, electronic customs documentation and cross-border payment acceptance. UPI services were launched in Sri Lanka in February 2024. Such initiatives can facilitate tourism and small transactions, but their reach depends on participating banks, merchants and applicable rules. Cybersecurity, data protection and grievance redress must accompany interoperability.

5. Constraints and strategic risks

Political mistrust remains the largest non-physical barrier. India–Pakistan tensions restrict overland regional integration, while SAARC’s institutional stagnation limits region-wide agreements. Changes in governments and domestic political narratives elsewhere can also delay projects or portray cooperation as excessive dependence on India. Bilateral and subregional mechanisms are more workable in many cases, but cannot entirely substitute for broader political reconciliation.

Implementation difficulties include land acquisition, contractor capacity, funding coordination, difficult terrain and weak last-mile links. Ministries, state governments, customs agencies and neighbouring administrations may work on different schedules. Border procedures and non-tariff barriers can neutralise gains from better roads. Conflict in Myanmar further demonstrates how security conditions can render completed assets underused.

Strategically, Chinese infrastructure financing and the Belt and Road Initiative influence regional choices. India objects to the China–Pakistan Economic Corridor passing through territory it claims in the former princely state of Jammu and Kashmir. Nevertheless, assessing every neighbouring project only through competition with China is inadequate. India’s credibility depends on transparent terms, respect for sovereignty, timely delivery and benefits perceived by host communities.

Environmental and social risks include habitat fragmentation, river disturbance, displacement and climate vulnerability. Border communities should not bear concentrated costs while distant commercial centres capture most benefits.

6. Policy priorities and GS-II assessment

India should prioritise completion and utilisation over announcement-driven diplomacy. Corridor planning must integrate transport infrastructure with customs reform, warehousing, feeder routes and predictable transit rights. Joint monitoring mechanisms should assess cargo volumes, journey times, reliability and local employment rather than counting only sanctioned projects.

A differentiated approach is necessary: hydropower and grid links suit Himalayan partnerships; railways and waterways offer advantages with Bangladesh; maritime and digital services are important for island neighbours. Consultation with northeastern and other border states can align diplomacy with local development needs. Climate-resilient design, transparent procurement and affordable maintenance should be built into project appraisal.

For a balanced Mains answer, connectivity should be presented as both a development instrument and a strategic relationship. Its success requires the convergence of infrastructure, institutions and trust. The strongest neighbourhood policy makes India a dependable partner while preserving the agency of neighbouring countries and ensuring that integration delivers visible gains to ordinary citizens.
