When Indonesian Sukhoi fighter jets scrambled to escort Indian Prime Minister Narendra Modi’s aircraft into Jakarta airspace, the spectacle flashed across television screens as a textbook display of diplomatic pageantry. Superficially, it was a grand welcome. Beneath the ceremonial smoke and mirrors, however, lies a calculated geopolitical maneuver aimed directly at Beijing. This military escort was not merely a polite greeting for a visiting dignitary; it was a loud, deliberate signal of a deepening defense alignment between New Delhi and Jakarta, two capitals increasingly unnerved by China's aggressive maritime expansion in the Indo-Pacific.
For decades, Southeast Asian diplomacy operated under a quiet status quo. Nations sought to balance their economic reliance on China with their security anxieties. But that balance is breaking down. Indonesia’s decision to accord Modi a reception typically reserved for wartime allies reveals how rapidly Jakarta is recalibrating its foreign policy. They need a counterweight. India, with its expanding naval footprint and willingness to confront Chinese overreach, fits the bill perfectly.

Decoding the Escort Protocol
Military escorts for foreign heads of state are rare. They are costly, logistically demanding, and fraught with political baggage. When a nation deploys its frontline fighter aircraft to flank a foreign leader's plane, it communicates explicit alignment to global intelligence agencies.
Indonesia deployed its Russian-made Sukhoi Su-30 vehicles for the mission. These are the same jets Jakarta frequently scrambles to intercept unauthorized Chinese vessels encroaching upon its Exclusive Economic Zone (EEZ) near the Natuna Islands. By using these specific assets to welcome the Indian Prime Minister, Indonesian defense planners connected the dots for anyone watching.

This gesture marks a departure from Indonesia's traditional bebas-aktif (independent and active) foreign policy doctrine. Historically, Jakarta avoided the appearance of choosing sides in great power rivalries. But the persistent incursions of the Chinese coast guard and fishing fleets into Indonesia's northern waters have forced a shift. The grand welcome was a public demonstration that Jakarta is no longer averse to flaunting its security partnerships.
The Shared Anxiety of Maritime Encroachment
To understand why Jakarta rolled out the red carpet, one must look at the maritime map. Both India and Indonesia sit at critical chokepoints of global trade. India dominates the Indian Ocean sea lanes, while Indonesia controls the Malacca, Sunda, and Lombok straits.
China's "String of Pearls" strategy in the Indian Ocean has long troubled New Delhi. Similarly, Beijing’s unilaterally claimed Nine-Dash Line overlaps significantly with Indonesia’s economic waters. This shared vulnerability has transformed a historically polite diplomatic relationship into a transactional security alliance.
Consider the Sabang port project. India has been quietly investing in the development of a deep-sea port at Sabang, located at the northern tip of Sumatra, right at the entrance of the Strait of Malacca. It is a brilliant piece of geography. For India, access to Sabang provides a vantage point right on the doorstep of the world's busiest maritime highway. For Indonesia, partnering with India to develop this infrastructure injects a powerful naval deterrent into a vulnerable sector without explicitly inviting the US military, which would trigger domestic political backlash.
Weapons and Submarines over Words
Diplomatic communiqués are cheap. Hardware is expensive. The true metric of the India-Indonesia relationship is found in their accelerating defense procurement and joint exercises.
Indonesia has watched closely as India successfully exported its BrahMos supersonic cruise missiles to the Philippines. Jakarta wants in on similar arrangements. Discussions regarding Indonesia’s acquisition of the BrahMos system have quietly progressed from theoretical bureaucratic talks to active defense ministry negotiations. Equipping Indonesian coastal batteries or naval vessels with Indo-Russian supersonic missiles would fundamentally alter the tactical calculus for Chinese vessels entering the North Natuna Sea.
- Joint Naval Patrols: The Samudra Shakti bilateral exercises have grown in complexity, moving from basic communication drills to advanced anti-submarine warfare simulations.
- Coordinated Patrols (CORPAT): Conducted twice a year near the International Maritime Boundary Line, these patrols ensure that both navies can operate seamlessly during a maritime crisis.
- Logistical Access: A reciprocal logistics agreement allows Indian warships to refuel and turn around at Indonesian ports, extending New Delhi’s operational reach into the Western Pacific.
This is not a formal treaty. It is a network of interlocking defense arrangements. It allows both nations to maintain plausible deniability regarding an anti-China coalition while building the infrastructure needed to operationalize one at a moment's notice.
The Limits of the New Delhi-Jakarta Axis
It would be an error to view this relationship as a flawless, unbreakable wall against Beijing. Major friction points remain.
Indonesia’s economy remains deeply intertwined with Chinese capital. Beijing is Jakarta’s largest trading partner and a massive investor in its critical infrastructure, particularly in the nickel mining and refining sectors vital to Indonesia's electric vehicle ambitions. President Joko Widodo's administration, and the leaders following him, cannot afford an open economic war with China.
Furthermore, India’s domestic political landscape and its treatment of minority populations occasionally trigger friction in Muslim-majority Indonesia. While Jakarta’s foreign policy elite compartmentalizes these issues in favor of hard-nosed realism, public pressure can tie the government's hands during times of acute domestic tension.
India also faces resource constraints. New Delhi is simultaneously managing a volatile land border with China in the Himalayas and trying to project power across the entire Indian Ocean. Whether the Indian Navy can consistently spare the assets to maintain a persistent, reassuring presence in Southeast Asian waters remains an open question.
A New Blueprint for Middle Powers
The fighter jet escort over Jakarta signals a broader trend in global politics. Middle powers are no longer waiting for Washington or Beijing to dictate the terms of security in Asia. They are taking matters into their own hands, building horizontal alliances to protect their sovereignty.
By honoring Modi with a combat aircraft escort, Indonesia signaled that it views India not just as a trading partner, but as a security anchor. It proved that defense diplomacy has moved past formal dinners and into the realm of tactical signaling. The message sent from the cockpits of those Sukhois was heard clearly in New Delhi, and even more clearly in Beijing. Turn back the next time you think about entering these waters.
