Ancient Roots and Cultural Bridges

The bond between India and Iran is not a modern construct; it is a profound historical connection that predates formal nation-states. Ties between both ancient Persia and ancient India date back millennia, fostering a rich tapestry of cultural, linguistic, and philosophical exchanges. The migration of Indo-Aryan peoples, the spread of Zoroastrianism, and the flourishing trade routes like the Silk Road facilitated an unparalleled cross-pollination of ideas, goods, and traditions. The Persian language, Farsi, profoundly influenced many Indian languages, particularly Urdu, and Persian art, architecture, and poetry left an indelible mark on Indian culture, most notably during the Mughal era. One significant aspect of this historical connection is the presence of the Parsi community in India, descendants of Zoroastrians who migrated from Persia to India to escape persecution. Their story is a testament to the enduring sanctuary India offered. This historical empathy was reciprocated, as exemplified by Reza Shah, who was sympathetic to Indian Zoroastrians (Parsis) and actively encouraged their return to Iran to invest and help develop the country's economy. In 1932, he invited Dinshah Irani, a Parsi leader and founder of the Iranian Zoroastrian Anjoman and the Iran League in India, to visit Iran as part of a Parsi delegation. This act underscored the deep-seated cultural and historical affinity that transcends political boundaries, forming a unique aspect of the India-Iran relationship. This historical depth provides a robust foundation upon which modern diplomatic ties have been built, making the current relationship between India and Iran more than just transactional; it is deeply rooted in shared heritage.

Diplomatic Foundations and Early Engagement

Following India's independence, the establishment of formal diplomatic relations with Iran on March 15, 1950, marked a new chapter in their long-standing association. In the initial decades, both nations, emerging from colonial shadows, found common ground in non-alignment and the pursuit of independent foreign policies. While Iran initially leaned towards Western alliances during the Cold War, India maintained its stance of strategic autonomy. Despite these differing alignments, bilateral engagement continued, primarily driven by economic cooperation and a shared understanding of regional stability. The Islamic Revolution in Iran in 1979 introduced a new paradigm, challenging India to adapt its diplomatic approach. While the world watched with apprehension, India maintained its pragmatic engagement, recognizing Iran's strategic importance and its role in the broader Middle East. This period saw the strengthening of cultural ties and people-to-people connections, even as geopolitical shifts began to redefine international relations. India's consistent policy has been to engage with Iran on a bilateral basis, focusing on areas of mutual interest while respecting its internal affairs. This foundational period laid the groundwork for the complex yet enduring relationship that India and Iran share today, characterized by a mix of cooperation and cautious navigation of global pressures.

The Economic Lifeline: Energy and Trade

For decades, energy security has been a cornerstone of the economic relationship between India and Iran. India is highly dependent on oil imports, with over 80 percent of its crude oil supply coming from external sources. Historically, Iran was a crucial and reliable supplier of crude oil to India, offering competitive prices and favorable payment terms. This dependency underscored the strategic importance of Iran to India's energy security and economic growth. The trade basket between the two nations has traditionally been dominated by Indian imports of Iranian oil and exports of agricultural products, pharmaceuticals, and machinery. However, the US' sanctions on Iran have significantly affected India’s relations, particularly impacting this vital energy trade. It’s true that India drew down energy imports from Iran to avoid the risk of U.S. secondary sanctions, a move that severely curtailed a previously robust trade avenue. Despite this, India has major interests in Iran and further afield in the Middle East, recognizing Iran's geographical advantage as a gateway to Central Asia and Afghanistan. This strategic vision has led to continued focus on non-sanctionable areas of cooperation, particularly in connectivity.

Connectivity Projects and Strategic Ports

Beyond oil, trade and connectivity have defined New Delhi’s ties with Tehran. The Chabahar Port, located on Iran’s southeastern coast, is a prime example of this strategic cooperation. Developed with significant Indian investment, Chabahar offers India a crucial alternative trade route to Afghanistan and Central Asia, bypassing Pakistan. This port is not merely a commercial venture but a geopolitical imperative, enabling India to expand its economic and strategic footprint in the region. The development of the International North-South Transport Corridor (INSTC), a multi-modal network connecting India, Iran, Azerbaijan, Russia, Central Asia, and Europe, further exemplifies the shared commitment to enhancing regional connectivity. This corridor aims to reduce transit time and costs for trade, unlocking immense economic potential for all participating nations. Despite the challenges posed by sanctions, India has consistently advocated for the continued development of Chabahar and the INSTC, viewing them as vital arteries for regional trade and stability, underscoring the long-term economic vision that binds India and Iran.

Geopolitical Convergence and Regional Security

The geopolitical landscape of Asia presents several areas where India and Iran share common strategic interests, particularly concerning regional security and stability. Iran, which shares borders with Afghanistan and Pakistan, is a key player in the region, wielding significant influence over developments in its immediate neighborhood. Both India and Iran have a vested interest in a stable, peaceful, and inclusive Afghanistan, free from the influence of extremist elements.

Addressing Common Threats

India and Iran share common concerns about the Taliban’s Sunni extremism and Pakistan’s role in Afghanistan. Both nations have historically supported non-Taliban factions and have advocated for a broad-based government in Kabul that represents all ethnic groups. The rise of extremist groups and the potential for regional instability emanating from Afghanistan pose direct threats to the security interests of both New Delhi and Tehran. This shared concern forms a crucial pillar of their strategic dialogue, leading to intelligence sharing and coordinated diplomatic efforts on Afghan affairs. Beyond Afghanistan, both countries also share a common interest in combating terrorism and drug trafficking, which often originate from the same unstable regions. Their cooperation extends to maritime security in the Indian Ocean and the Persian Gulf, vital arteries for global trade. This convergence of security interests, despite broader geopolitical pressures, highlights the pragmatic nature of the India-Iran relationship, where shared threats often override external complications.

Navigating the Sanctions Labyrinth

Perhaps the most significant challenge to the India-Iran relationship has been the imposition of stringent sanctions by the United States on Iran. These sanctions, primarily aimed at Iran's nuclear program and its alleged support for regional proxies, have had a profound impact on India's ability to engage freely with Tehran. The US' sanctions on Iran have affected India’s relations, forcing New Delhi to make difficult choices between its strategic partnership with the US and its long-standing ties with Iran. It’s true that India drew down energy imports from Iran to avoid the risk of U.S. secondary sanctions, a pragmatic decision driven by the need to protect its economic interests and maintain good relations with a crucial global partner like the United States. This situation has put New Delhi in a precarious position, as it seeks to balance its diverse foreign policy objectives. While India has complied with the sanctions regime to a large extent, it has also consistently advocated for diplomatic solutions to the Iranian nuclear issue and expressed concerns about the unilateral nature of some sanctions.

Balancing Act with Global Powers

India maintains amicable relations with both Israel and Iran, which is the result of a delicate balancing act stretching back many years. This unique diplomatic posture allows India to engage with all parties in the complex Middle East region without being forced to choose sides. This balancing act is crucial for India's strategic autonomy and its ability to pursue its national interests independently. While navigating the US sanctions on Iran, India has continued to emphasize the importance of Iran for regional stability and connectivity, particularly through projects like Chabahar Port, which has often received carve-outs from certain sanctions due to its humanitarian and regional connectivity significance. This demonstrates India's resolve to maintain a working relationship with Iran despite external pressures, underscoring its commitment to strategic independence in its foreign policy.

Indian Diaspora in Iran and Consular Support

The human element forms an important, albeit often understated, aspect of the India-Iran relationship. More than 4,000 Indian nationals are said to be living in Iran, and half of them are students, pursuing higher education in various fields. This substantial diaspora contributes to the cultural and economic ties between the two nations, fostering people-to-people connections that transcend political complexities. However, in times of heightened geopolitical tension or crisis, the safety and well-being of Indian nationals become a paramount concern for the Indian government. The MEA said Indian nationals in Iran are advised to stay in touch with the Indian Embassy in Tehran through its emergency helpline, and with the MEA’s 24x7 control room. Earlier, on Tuesday, India had asked its nationals to leave Tehran, reflecting a proactive approach to ensuring their safety amidst regional uncertainties. The Indian Embassy in Iran is equipped to provide comprehensive consular support, including evacuation efforts when necessary. The embassy may be contacted either on the Telegram channel or over the emergency contact numbers, ensuring that Indian citizens have multiple avenues for assistance. This commitment to its diaspora underscores India's responsible approach to its citizens abroad and highlights the practical implications of maintaining diplomatic ties with countries like Iran, where regional dynamics can shift rapidly.

Multilateral Platforms and Shared Visions

Beyond bilateral engagements, India and Iran also interact on various multilateral platforms, which provide additional avenues for cooperation and dialogue. One significant example is the Shanghai Cooperation Organization (SCO), a political and security bloc founded in 2001. The SCO consists of China, Belarus, India, Iran, Kazakhstan, Kyrgyzstan, Pakistan, Russia, Tajikistan, and Uzbekistan. Iran is the most recent full member, having joined the organization, which marks a significant development in its regional and international integration. India's membership in the SCO alongside Iran offers a crucial platform for discussing regional security issues, counter-terrorism efforts, and economic cooperation, often outside the direct purview of Western influence. This forum allows both nations to coordinate on issues of common concern, such as stability in Central Asia and Afghanistan, and to promote a multi-polar world order. Their participation in such blocs underscores a shared vision for a more balanced global power structure and provides a mechanism for dialogue that can mitigate bilateral tensions arising from external pressures. The SCO, therefore, serves as an important bridge, reinforcing the strategic alignment between India and Iran on broader regional and global issues.

The Future of India-Iran Relations

The relationship between India and Iran is a testament to the enduring power of historical connections and strategic imperatives. Despite the formidable challenges posed by international sanctions and complex geopolitical dynamics, the two nations have consistently found ways to maintain and evolve their ties. India's commitment to strategic autonomy, its significant energy needs, and its vision for regional connectivity through projects like Chabahar Port ensure that Iran will remain a vital partner in its foreign policy calculus. Looking ahead, the future of India-Iran relations will likely be characterized by continued pragmatism and a focus on areas of mutual benefit that are less susceptible to external pressures. While the shadow of sanctions may persist, both countries are keen to explore new avenues for cooperation in technology, pharmaceuticals, agriculture, and cultural exchange. The shared concerns regarding regional security, particularly in Afghanistan, will continue to bind them strategically. As New Delhi navigates its path towards becoming a leading global power, its ability to maintain robust, yet carefully balanced, relationships with key regional players like Iran will be crucial for its long-term strategic interests and its vision for a stable and prosperous Asian continent. The intricate dance between historical affinity, economic necessity, and geopolitical realities will continue to define the compelling narrative of India and Iran.
