India is funding and providing technical expertise for the restoration of Indonesia's Prambanan Temple to anchor its "Act East" policy and counter Chinese dominance in Southeast Asia through strategic cultural diplomacy. While official press releases frame the initiative as a purely historical and spiritual reunion between two ancient civilizations, the reality on the ground is entirely geopolitical. New Delhi is using shared Hindu-Buddhist heritage to build soft-power equity in Jakarta, aiming to secure maritime choke points and economic partnerships that traditional diplomacy has failed to lock down.
By taking a direct role in preserving Southeast Asia’s largest Shiva temple, India is positioning itself as the rightful civilizational custodian of the region, challenging Beijing's infrastructure-heavy footprint with a narrative of deep-rooted, non-coercive partnership. Building on this theme, you can find more in: Why the India Iran Civilizational Bond Matters More Than Ever.
Civilizational Bonds as Hard Currency
Foreign policy is rarely built on sentimentality. When Indian archaeologists and state funds arrive at the Prambanan compound in Central Java, they are carrying more than just ground-penetrating radar and stone-preservation chemicals. They are carrying a counter-narrative to China's Belt and Road Initiative.
For the last two decades, Beijing has bought influence across Southeast Asia through massive port, rail, and highway projects. Indonesia, the largest economy in ASEAN, accepted tens of billions of dollars in Chinese investments, notably for the Jakarta-Bandung high-speed rail line. But infrastructure loans come with strings, sovereign friction, and local resentment. Observers at USA Today have shared their thoughts on this situation.
New Delhi cannot match China’s financial muscle dollar for dollar. It can, however, leverage a shared history that pre-dates modern borders by a millennium. Prambanan, built in the 9th century by the Sanjaya dynasty, stands as a massive stone testament to the historical flow of Indian culture, religion, and architecture across the Indian Ocean. By embedding its state agencies in the preservation of this UNESCO World Heritage site, India reminds Indonesia of a time when the two regions were bound by trade and faith, not debt.
This is cultural diplomacy weaponized for the twenty-first century. It changes the conversation from economic dependency to mutual respect.
The Mechanics of Soft Power Projection
The Archaeological Survey of India (ASI) serves as the vanguard for this strategy. The agency has spent decades restoring temples outside its borders, including Angkor Wat in Cambodia and Vat Phou in Laos. These are not charity projects. They are highly calculated diplomatic deployments.
When the ASI operates abroad, it establishes a long-term bureaucratic and physical presence in the host country. Indian engineers, historians, and diplomats work side-by-side with local ministries. This creates a bureaucratic intimacy that standard diplomatic summits cannot achieve.
- Institutional access: Years of joint preservation work create direct channels into host-country ministries of culture, tourism, and foreign affairs.
- Local goodwill: Unlike a foreign-owned factory or a toll road, temple restoration directly honors local identity, generating positive domestic press that shields the foreign power from political backlash.
- Securing the maritime flank: Indonesia controls the Malacca, Sunda, and Lombok straits. For India, ensuring Jakarta remains neutral or friendly is essential to monitoring Chinese naval movements entering the Indian Ocean.
The Friction Between Faith and Sovereign Reality
The initiative is not without structural friction. Prambanan is an ancient Hindu temple, but modern Indonesia is the world’s most populous Muslim-majority nation. Managing the optics of a foreign Hindu power restoring a monument within an Islamic society requires delicate political footwork.
The Indonesian state treats Prambanan primarily as a cultural treasure, an architectural marvel, and a major driver of international tourism. It is a symbol of Bhinneka Tunggal Ika—Unity in Diversity—the foundational national motto of Indonesia. Jakarta welcomes foreign expertise, but it is highly sensitive to any narrative that implies Indonesia needs an external, religious custodian to manage its own heritage.

| THE TWO FACES OF TEMPLE RESTORATION |
+------------------------------------------------------------+
| INDIA'S STRATEGIC VIEW | INDONESIA'S DOMESTIC VIEW |
+------------------------------+-----------------------------+
| • Civilizational leadership | • National pride & identity |
| • Act East policy anchor | • Domestic tourism revenue |
| • Countering Chinese clout | • Proof of pluralism |
| • Maritime security alignment| • Sovereign autonomy |
+------------------------------------------------------------+
New Delhi must tread carefully. If India’s domestic political rhetoric leans too heavily into Hindu nationalism while discussing foreign restorations, it risks alienating the secular and Islamic framework of Indonesian governance. The moment the restoration project looks like religious triumphalism rather than international conservation, Jakarta will pull the plug.
The Architectural Battlefield
The physical restoration of a 9th-century temple is an agonizingly slow process. Prambanan was devastated by an earthquake in 2006, leaving many of its smaller shrines as piles of scattered volcanic stone. The methodology used to rebuild these structures is itself a point of subtle contention.
The Dutch colonial authorities began the reconstruction using anastylosis, a method where a ruined building is dismantled and rebuilt using the original architectural fragments alongside minimal new materials. India’s archaeological establishment has historically favored a more interventionist approach, sometimes replacing missing elements with new carvings to restore the spiritual wholeness of a structure.
Reconciling these two schools of conservation requires intense technical negotiation. These technical debates over stone joins and mortar compositions serve as a useful proxy for the broader diplomatic relationship. They force both nations to sit at the negotiating table month after month, solving micro-problems and building institutional trust far away from the volatile headlines of global trade wars.
The Long Game for the Indian Ocean
Look at a map of the Indo-Pacific. India sits at the center of the western rim; Indonesia anchors the eastern gate. The waters that connect them are the busiest shipping lanes on the planet.

India’s maritime doctrine relies heavily on preventing the encirclement of its coastline by foreign naval bases. By funding high-profile heritage projects in Indonesia, New Delhi secures the cultural flank of a comprehensive strategic partnership that includes joint naval exercises, the development of the Sabang deep-sea port, and increased military intelligence sharing.
It is a classic asymmetric strategy. India cannot outbid its northern rival in infrastructure spending, so it shifts the playing field to an arena where its rival cannot compete. Beijing’s officially atheist state apparatus cannot claim a shared spiritual lineage with the Hindu and Buddhist history of Southeast Asia. India can.
The Limits of Stone Diplomacy
But soft power has hard limits. Preserving ancient temples does not erase the immediate economic realities facing modern nations. Indonesia still requires massive capital injections for its green energy transition, its new capital city project in Borneo, and its domestic manufacturing sectors.
A beautifully restored Shiva temple cannot replace a state-of-the-art semiconductor facility or a multi-billion-dollar mining investment. If India wishes to convert cultural goodwill into concrete strategic alignment, it must eventually back up its archaeologists with corporate investors and trade concessions.
Governments in Jakarta change. Political winds shift. But the massive stone spires of Prambanan have stood for over a thousand years, outlasted empires, kingdoms, and colonial occupations. By linking its modern destiny to these enduring stones, India is making a generational bet that long after the current infrastructure loans have been settled, the civilizational tie will remain unbroken.
The true success of the Prambanan project will not be measured by how many tourists visit the site or how cleanly the ancient volcanic rocks are joined together. It will be measured in the quiet access Indian naval vessels receive at Indonesian ports and the resilience of diplomatic ties when geopolitical pressures push both nations to their limits. New Delhi is betting that a foundation built on ancient stone is far more secure than one built on modern paper money.
