1. India's 'Neighborhood First' and Connect Central Asia Policies (basic)
To understand India's modern foreign policy, we must first look at its geopolitics. While India is a maritime powerhouse in the south, its land connectivity to the west and north has historically been restricted due to difficult terrain and strained relations with Pakistan. To overcome this "geographical cage," India utilizes two primary pillars: the 'Neighborhood First' policy and the 'Connect Central Asia' policy.
The 'Neighborhood First' policy is centered on the principle that India's growth is inextricably linked to the peace and prosperity of its immediate neighbors. This isn't just about diplomacy; it is about physical connectivity—building roads, railways, and energy grids that link the Indian economy with countries like Afghanistan, Bangladesh, and Nepal. While early foreign policy under Jawaharlal Nehru focused on preserving sovereignty and non-alignment Politics in India since Independence, India's External Relations, p.57, modern iterations prioritize pragmatic economic integration and being a "first responder" in the region.
Moving beyond the immediate circle, the 'Connect Central Asia' policy (launched in 2012) targets the "extended neighborhood" comprising five landlocked, energy-rich nations: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan Indian Polity, Foreign Policy, p.611. Because India lacks a direct land border with these nations, it invests in massive infrastructure projects to bypass obstacles. A prime example is the International North-South Transport Corridor (INSTC) and strategic road projects like the Zaranj-Delaram Highway in Afghanistan. These initiatives are designed to create a trade bridge from Indian ports to Central Asian markets via Iran, effectively bypassing the transit restrictions often imposed by Pakistan Indian Polity, Foreign Policy, p.612.

2. The Strategic Role of Afghanistan in Regional Connectivity (basic)
To understand why Afghanistan is often called the 'Heart of Asia,' we must first look at its geography. It sits at the intersection of three major regions: South Asia, Central Asia, and the Middle East. Historically, this made Afghanistan a 'buffer state'—a neutral zone between two powerful empires. In the 19th century, during the 'Great Game,' the British Empire in India and the Russian Empire in Central Asia competed for influence here, as the British saw it as a vital advanced post to check military threats and promote commercial interests Modern India, Bipin Chandra, India And Her Neighbours, p.174. Even today, though its borders with South Asia are less geographically distinct than the Himalayas, it remains central to any discussion on regional stability and trade Contemporary World Politics, Contemporary South Asia, p.30.
In the modern era, Afghanistan’s strategic role has shifted from being a buffer to becoming a connectivity hub. Because India lacks direct land access to Central Asian markets due to the denial of transit rights by Pakistan, Afghanistan provides an alternative gateway. This is best exemplified by the Zaranj-Delaram Highway (Route 606). Constructed by India’s Border Roads Organisation (BRO) and completed in 2009, this 218-km road connects the Iranian border at Zaranj to Delaram. From Delaram, goods can access the Garland Highway—Afghanistan’s circular road system that links its major cities like Kabul, Kandahar, and Herat.
This infrastructure is part of a much larger strategy involving the Iranian port of Chabahar. By shipping goods to Chabahar and then moving them by road through Zaranj to the Afghan interior, India effectively bypasses Pakistan. Beyond just roads, there are long-term visions for a Trans-Asiatic Railway that could eventually link Istanbul to Bangkok via the region, reinforcing Afghanistan's potential as a transit corridor for energy and trade between the resource-rich Central Asian republics and the energy-hungry South Asian markets FUNDAMENTALS OF HUMAN GEOGRAPHY, Transport and Communication, p.60.
Key Takeaway Afghanistan acts as a strategic land bridge that allows India to bypass geographical barriers (like Pakistan) to reach Central Asian markets through the Chabahar-Zaranj-Delaram corridor.

3. Border Roads Organisation (BRO) and Overseas Projects (intermediate)
To understand the Border Roads Organisation (BRO), we must first look at its unique dual mandate. Established in May 1960, the BRO was not created as a mere civil engineering body, but as a specialized organization to accelerate economic development and strengthen defense preparedness through the rapid improvement of strategically important roads along India’s northern and north-eastern borders NCERT Class XII India: People and Economy, Transport and Communication, p.77. While most national highways are built for commercial volume, BRO roads are often lifelines for remote populations, integrating them with the mainland and ensuring military mobility in rugged, high-altitude terrains NCERT Class XII Fundamentals of Human Geography, Transport and Communication, p.57.
In recent decades, the BRO’s expertise has been weaponized as a tool of "Soft Power" and strategic diplomacy. India utilizes the BRO to execute high-stakes infrastructure projects in neighboring countries like Afghanistan, Bhutan, Myanmar, and Tajikistan. These are not merely developmental gifts; they are strategic maneuvers to create alternative connectivity corridors. A prime example is the Zaranj-Delaram Highway (Route 606) in Afghanistan. Completed in 2009 despite immense security threats, this 218-km road connects the town of Zaranj on the Iranian border to Delaram, which sits on Afghanistan's Garland Highway (the circular road connecting major cities like Kabul, Kandahar, and Herat).
The strategic logic behind such overseas projects is often geopolitical bypass. Historically, India’s trade with Afghanistan and Central Asia was stifled because Pakistan denied India land-transit rights. By building the Zaranj-Delaram road, India created a vital link to the Chabahar Port in Iran. This allows Indian goods to be shipped to Iran and then trucked directly into the heart of Afghanistan and beyond, completely circumventing the need for Pakistani territory Majid Husain, Geography of India, Transport, Communications and Trade, p.1.

4. Chabahar Port: India's Gateway to the West (intermediate)
To understand the significance of the
Chabahar Port, we must first look at the map of South Asia. India faces a major 'geographical blockade' when trying to trade with Afghanistan and the resource-rich Central Asian Republics. Since overland transit through Pakistan is often restricted or denied for Indian goods, India needed a reliable maritime-cum-land bypass. Chabahar, located on Iran's southeastern coast in the Gulf of Oman, serves as this vital
'Gateway to the West'. Unlike other regional ports, it is a deep-sea port that sits outside the sensitive
Strait of Hormuz, making it less vulnerable to maritime blockades during regional tensions.
The project is more than just a harbor; it is a multi-modal transit corridor. In 2015, India and Iran signed a Memorandum of Understanding for its development Indian Economy, Nitin Singhania, Infrastructure, p.461, which culminated in the landmark 2016 Trilateral Agreement between India, Iran, and Afghanistan. This agreement established a transit and transport corridor, allowing Indian goods to reach Afghan soil without ever touching Pakistani territory Geography of India, Majid Husain, India–Political Aspects, p.59. For India, this isn't just about trade; it is a strategic counter-response to the Gwadar Port in Pakistan, developed under the China-Pakistan Economic Corridor (CPEC).
A critical 'missing link' in this corridor was the Zaranj-Delaram Highway (Route 606) in Afghanistan. Constructed by India’s Border Roads Organisation (BRO), this 218-km road connects the town of Zaranj (on the Iranian border) to Delaram. From Delaram, goods can enter Afghanistan’s 'Garland Highway,' which links major cities like Kabul, Kandahar, and Herat. By funding and building this infrastructure, India ensured that once cargo lands at Chabahar and travels through Iran to the border, there is a high-quality road waiting to carry it deep into the Afghan heartland and eventually toward Central Asian markets Geography of India, Majid Husain, Transport, Communications and Trade, p.2.
2009 — BRO completes the Zaranj-Delaram Highway, providing the first major road link for the corridor.
2015 — India and Iran sign an MOU to develop two berths at Chabahar Port.
2016 — Historic Trilateral Transit Agreement signed between India, Iran, and Afghanistan in Tehran.
2018 — India officially takes over operational control of a portion of the Shahid Beheshti terminal at Chabahar.
Key Takeaway Chabahar Port, paired with the India-built Zaranj-Delaram highway, provides India with a strategic trade route to Afghanistan and Central Asia that completely bypasses Pakistan.

5. INSTC and the Ashgabat Agreement (exam-level)
The
International North-South Transport Corridor (INSTC) is a 7,200-km multi-modal transport network (ship, rail, and road) designed to connect the Indian Ocean and the Persian Gulf to the Caspian Sea via Iran, and onward to Russia and Northern Europe. Traditionally, Indian goods destined for Russia or Europe have to traverse the Suez Canal, a journey that is both time-consuming and expensive. The INSTC serves as a strategic alternative, bypasses the traditional bottlenecks, and is estimated to reduce carriage costs by 30% and transit time by nearly 40%. Central to this vision is India's investment in the
Chabahar Port in Iran, which acts as the maritime gateway to this corridor, allowing India to trade with Central Asia and Afghanistan without relying on land routes through Pakistan
Geography of India, Majid Husain (9th Ed), Chapter 12, p.2.
To complement the physical infrastructure of the INSTC, India joined the
Ashgabat Agreement in 2018. This is a multimodal transport agreement between Oman, Iran, Turkmenistan, Uzbekistan, and Kazakhstan. By joining, India effectively synchronized its maritime reach with the rail and road networks of Central Asia. While the INSTC focuses on the North-South axis toward Russia, the Ashgabat Agreement facilitates East-West connectivity into the heart of the Eurasian landmass. Together, these initiatives aim to transform India from a maritime power into a major player in continental Eurasian trade, providing a reliable link to the resource-rich "Stans"

One of the most critical land links in this ecosystem is the
Zaranj-Delaram Road (Route 606) in Afghanistan. Constructed by India’s Border Roads Organisation (BRO), this 218-km highway connects Zaranj on the Iranian border to Delaram, which then hooks into Afghanistan's
Garland Highway. This piece of infrastructure is the "missing link" that allows goods arriving at Iran's ports to reach major Afghan cities like Kabul and Kandahar. For India, this road is not just asphalt; it is a strategic bypass that ensures humanitarian aid and commercial trade can reach Afghanistan independently of any third-party transit restrictions
Geography of India, Majid Husain (9th Ed), Chapter 12, p.2.
Key Takeaway The INSTC and Ashgabat Agreement together form a dual-layered strategy: the former provides a vertical corridor to Russia/Europe, while the latter provides horizontal access to Central Asia, both anchored by the strategic nodes of Chabahar and the Zaranj-Delaram road.

6. The Zaranj-Delaram Highway (Route 606) (exam-level)
To understand the Zaranj-Delaram Highway (Route 606), one must first look at a map of South Asia. India has long faced a geographical challenge: it is separated from landlocked Afghanistan and the resource-rich Central Asian Republics by Pakistan, which has historically denied India land transit rights. To overcome this "geographical cage," India invested in a strategic alternative—the Chabahar Port in Iran and the subsequent road network leading into Afghanistan.
The highway itself is a 218-km stretch located in the Nimruz province of Afghanistan. It was constructed by India’s Border Roads Organisation (BRO), an agency that specializes in infrastructure development in challenging and high-altitude terrains Geography of India, Majid Husain, Transport, Communications and Trade, p.2. Completed in 2009 under immense security pressure, the road connects Zaranj (on the border with Iran) to Delaram. This is not just a local road; it is a gateway that links to the Garland Highway—Afghanistan’s circular road system that connects its major hubs: Kabul, Kandahar, Herat, and Mazar-i-Sharif.
The strategic significance of this project is three-fold:
- Bypassing Pakistan: It provides India with a reliable trade route to Afghanistan and Central Asia that does not depend on Pakistani territory.
- Economic Integration: By connecting the Iranian port of Chabahar to the Afghan heartland, it reduces Afghanistan's dependence on the Port of Karachi, thereby shifting regional trade dynamics.
- Humanitarian & Strategic Presence: It facilitates the delivery of Indian humanitarian aid (like wheat and medicines) and establishes India as a key partner in regional stability and reconstruction.

7. Solving the Original PYQ (exam-level)
This question beautifully integrates what you have just learned about India's strategic infrastructure projects and its 'Connect Central Asia' policy. In our concept sessions, we discussed how the Border Roads Organization (BRO) acts as an instrument of diplomacy by building critical assets in friendly neighboring countries. The Zaranj-Delaram road (Route 606) is the physical manifestation of this strategy. As noted in Geography of India, Majid Husain, this 218-km highway was a Herculean task completed by the BRO in 2009, making Statement I correct. By connecting Zaranj on the Iranian border to the Garland Highway in Afghanistan, it creates a vital trade corridor that links the Indian-backed Chabahar Port to major Afghan cities.
To arrive at the correct answer, you must apply the logic of strategic bypass. Statement III is correct because the road is specifically designed to open Afghan markets to Indian goods via Iran. This brings us to the common UPSC trap found in Statement II. A recurring theme in Indian foreign policy is the search for transit routes that do not depend on Pakistan, as Islamabad has historically denied India overland access to Kabul. Therefore, a project designed to bypass a bottleneck cannot, by definition, link through that bottleneck. This realization allows you to confidently eliminate Statement II and any options containing it.
By filtering out the 'Pakistan' distractor, you are left with (B) I and III only. This question tests more than just your memory of road names; it tests your understanding of why India spends thousands of crores on foreign soil—to secure energy security and market access independent of regional geostrategic hurdles. Always look for the strategic intent behind the infrastructure to avoid falling for simple geographic traps.
