Step into a taxi in Jakarta, battle the suffocating heat of the evening rush hour, and you will eventually hear it. It might come through a crackling radio or be hummed by a driver navigating the chaotic sea of motorbikes.
Kuch Kuch Hota Hai.
To a casual tourist, it is a fleeting moment of pop culture trivia. To anyone watching the tectonic shifts of global geopolitics, it is something entirely different. It is proof that before diplomats sign treaties, before navies coordinate patrols in the Indian Ocean, and before trade routes are carved out of open water, nations must first find a way to speak to each other's hearts.
We often view international relations as a cold calculus of GDP, military spending, and strategic choke points. We focus on the hard numbers. We analyze the policy papers. But we miss the human currents that make those policies possible in the first place. When Indian Prime Minister Narendra Modi stood before a gathering in Jakarta and invoked Shah Rukh Khan’s 1998 romantic blockbuster, he was not just making a clever pop-culture reference to get a quick round of applause. He was tapping into a deep, decades-old emotional reservoir that binds nearly two billion people across the Indian Ocean.
The Boy from Medan and the Tape Deck
Consider a hypothetical citizen named Agus. He is a forty-something shopkeeper living in Medan, North Sumatra. He has never been to Mumbai. He does not speak Hindi. Yet, if you play the opening chords of that iconic 90s title track, his eyes will light up. He remembers watching the movie on a grainy VHS tape as a teenager, weeping over a story of love, loss, and friendship that felt intensely familiar, despite originating thousands of miles away.
Agus’s experience is not an anomaly; it is the rule. When India opened its economy in the early 1990s, its cultural footprint expanded rapidly across Southeast Asia. Indonesia, with its own rich history of performance, music, and deep Hindu-Buddhist historical roots, did not just accept this cultural wave—it devoured it.
This is what scholars call soft power, but that term feels too clinical. It is better understood as a shared vocabulary. When people share the same stories, they stop viewing each other as foreign entities. They become predictable, relatable, and ultimately, trustworthy.
The historical ties run far deeper than modern cinema. Millennia before celluloid, Indian traders sailed with the monsoon winds to Sumatra and Java, bringing epics like the Ramayana and the Mahabharata. These stories became so deeply woven into the Indonesian identity that they form the basis of traditional Javanese wayang kulit (shadow puppetry). The language itself holds these secrets; Bahasa Indonesia is littered with Sanskrit words.
When modern Bollywood arrived, it didn’t feel like an alien invasion. It felt like an old friend returning in a brighter, louder outfit.
The Shift from Melody to Markets
But culture is merely the soil. The real question is what grows out of it.
For decades, India and Indonesia operated as friendly neighbors who rarely collaborated on anything of substance. They were co-founders of the Non-Aligned Movement in 1955, a diplomatic effort born out of the Cold War, but their economic and strategic ties remained stagnant. They looked past each other. India looked west toward Europe and America; Indonesia focused on its immediate Southeast Asian neighbors.
Then the world changed. The rise of new maritime tensions and the need for diversified supply chains forced both nations to look across the water.
Imagine the Indian Ocean not as a blank blue space on a map, but as a crowded highway. More than half of the world’s container ships and two-thirds of its oil shipments pass through these waters. Indonesia sits at the eastern gate of this highway, controlling the crucial Malacca Strait. India sits squarely in the middle, its peninsula stretching down like a massive pier into the shipping lanes.
If these two giants do not coordinate, the highway becomes vulnerable.
When policy experts discuss India’s "Act East" policy, they are talking about a deliberate pivot toward nations like Indonesia. It manifests in practical, unglamorous ways: upgrading the deep-sea port in Sabang, Indonesia, which sits a mere 90 nautical miles from India's Andaman and Nicobar Islands. It looks like joint naval exercises, shared maritime radar data, and bilateral trade that has surged past $30 billion.
The Friction in the Machinery
It is easy to romanticize this partnership, but the path is rarely smooth. Anyone who has managed an international business venture knows that shared history does not automatically equal shared interests.
India and Indonesia frequently bump heads over trade barriers. India’s agricultural sector is fiercely protective, often placing restrictions on Indonesian palm oil imports to shield its domestic farmers. Conversely, Jakarta frequently seeks to balance its trade deficits, occasionally imposing hurdles on Indian pharmaceuticals and automotive parts.
There is also the delicate dance of geopolitical alignment. India is a member of the Quad, alongside the United States, Japan, and Australia, aiming to balance a rising China. Indonesia, true to its historic "independent and active" foreign policy, fiercely guards its neutrality. Jakarta refuses to be drawn into a new Cold War, preferring to maintain deep economic ties with Beijing while simultaneously building security alliances with New Delhi and Washington.
It is a dizzying, high-stakes balancing act. This is where the emotional core matters most. When economic disputes arise or strategic perspectives diverge, the shared cultural baseline acts as a shock absorber. It prevents political friction from devolving into outright hostility. It allows leaders to sit at a table, smile, and remind each other that behind the disagreements over tariffs, they are still the people who sing the same songs.
The Geometry of Shared Progress
During his address, the Indian leader used a simple linguistic play on the film's title. Kuch kuch hota hai translates to "something happens." He noted that when India and Indonesia truly move in tandem, it leads to bahut kuch—meaning "a great deal happens."
It is a shorthand philosophy for a combined market of over 1.7 billion people.
Consider the digital revolution happening in both countries. India pioneered the Unified Payments Interface (UPI), a system that allowed hundreds of millions of unbanked citizens to enter the formal economy via simple mobile transactions. Indonesia has experienced its own massive digital boom, led by homegrown tech giants that transformed local commerce and transport.
When these two ecosystems collaborate, the potential is staggering. We are looking at the creation of a massive, interconnected digital marketplace that operates independently of Western or Chinese tech hegemony. It is about financial inclusion on a scale the world has never seen before.
This is not abstract futurism. It is happening in small steps. It is Indian fintech companies setting up shops in Jakarta. It is Indonesian tech talent training in Bengaluru. It is the quiet construction of a new digital architecture across the Indian Ocean.
The View from the Harbor
Go down to the port of Sabang at dusk. Watch the massive cargo ships silhouette against the setting sun as they prepare to enter the Malacca Strait.
It is quiet here, save for the rhythmic lapping of the waves against the concrete piers. But beneath that quiet lies the future of global trade and security. The decisions made in the government offices of New Delhi and Jakarta will dictate whether these waters remain safe, open, and prosperous for the next century.
It is a heavy, complex burden borne by politicians, generals, and CEOs. But its foundation remains remarkably simple. It rests on the shoulders of the millions of people who, despite differing religions, languages, and passports, can still look at one another, recognize a familiar melody, and feel instantly at home.
The music plays on, an invisible thread holding two giants together as they step into an uncertain world.
