Japanese Prime Minister Sanae Takaichi’s meeting with Indian Prime Minister Narendra Modi in New Delhi on July 2 produced a long list of agreements covering artificial intelligence, batteries, critical minerals, defense manufacturing, energy sustainability and financial cooperation.
While the deals made headlines, the bigger message was the changing geostrategic framework of the Indo-Pacific. Set against the backdrop of evolving China-Japan dynamics since Takaichi took office, her meeting with Modi underscored that the India-Japan convergence is structural and strategic.
The meeting signaled a search for a new economic security architecture in the Indo-Pacific – one that aims to manage impact and protect against vulnerability.
China’s growing willingness to use export controls, investment restrictions and other forms of economic coercion has reinforced concerns about concentrated production networks and technological dependence.
At the same time, the Trump administration’s transactional approach to alliances and burden-sharing — along with the symbolic shift to the “Pacific,” rather than the “Indo-Pacific,” in U.S. strategic nomenclature — has reminded regional partners that they can no longer assume continuity in Washington’s strategic priorities.
The central question facing the major Indo-Pacific nations is no longer who they associate with, but how they configure the technologies, industries, and production systems on which economic security ultimately depends.
Border technologies and digital-industrial architectures are emerging as instruments of geopolitical leverage because these platforms and networks are becoming inseparable from national security, economic systems, surveillance and intelligence gathering, commercial governance, and political influence.
The geography of these ecosystems and the interrelationships between them determine whether states possess the technological, industrial and resource base necessary to sustain impact. Together, they form the architecture that defines economic security and strategic vulnerability.
The defense-industrial dimension of the India-Japan deal is particularly revealing. The joint production of the UNICORN integrated naval antenna and communications mast is significant because it shows how industrial policy and defense policy are increasingly intertwined. The gap between civilian and military industrial ecosystems is steadily narrowing as technological competition itself becomes a deterrent.
The future balance of power in the Indo-Pacific will increasingly depend not just on military prowess or diplomatic outreach, but on who can configure and anchor resilient industrial ecosystems that link technology, resources, manufacturing and defense production between trusted partners.
Semiconductors, artificial intelligence, critical minerals, batteries, trusted digital infrastructure and defense manufacturing are becoming instruments of influence.
Tokyo isn’t just looking for an alternative investment destination in Asia. It is seeking partners capable of anchoring a resilient geographically distributed industrial ecosystem—one that can absorb geopolitical shocks without the dependencies and vulnerabilities that have emerged in existing supply chains and markets.
Herein lies the importance of the Modi-Takaichi summit as a framework for economic security and influence across the Indo-Pacific. It is about building complementary capabilities that provide a long-term defense against rival US-China axes, as commercial armaments and strategic vulnerabilities pose growing threats.
India and Japan occupy vital nodes in Asia’s industrial landscape outside of China. Their capabilities are, in some ways, complementary: Japan contributes capital, advanced manufacturing, precision engineering, and frontier technology, while India offers manufacturing scale, software capabilities, engineering talent, a large domestic market, and a strategic location linking the Western Pacific to the Indian Ocean.
These attributes make India less an alternative to China than a vital component of a more distributed Indo-Pacific production network – one that buffers against economic and national security vulnerabilities. New Delhi’s pursuit of defense, balancing and strategic autonomy between rival axes dominated by the US and China, combined with its economic prowess, gives it a unique position in Asia.
The Takaichi-Modi meeting could thus mark the beginning of a broader shift towards the integration of technological-defense-industrial systems across the larger Indo-Pacific economies seeking a hedge against the rival US-China axis. Takaichi’s interpretation of Japan’s Free and Open Indo-Pacific (FOIP) strategy reflects this change. Under Takaichi, economic security has become the defining characteristic of FOIP.
Strategic industries now occupy a central place in Japan’s strategic thinking, alongside maritime security. Consequently, FOIP has evolved from a framework for maintaining regional order to a framework for managing strategic vulnerability at a time when economic interdependence itself has become a source of geopolitical risk.
India fits well with Japan’s need to anchor a broader industrial ecosystem that does not replicate the concentration risks associated with China-dominated manufacturing networks. The agreements signed in New Delhi, therefore, represent more than an expansion of bilateral cooperation. They show how India and Japan are seeking to reconfigure strategic influence through technological-defense-industrial capabilities and not just diplomacy.
Neither India nor Japan seeks to diminish the central role of the US in the region. Both recognize that they cannot address global vulnerabilities arising from critical mineral dependencies, semiconductor supply chains, or technological concentration without American participation in the global technology and industrial architecture. Japan and India also understand the need for alliances that can last regardless of changes in US policy.
The Quad will remain a key framework of Indo-Pacific strategic coordination, centered on the China context. But its importance lies increasingly in facilitating cooperation between Asia’s larger industrial, technological and manufacturing systems and networks.
The agreements announced in New Delhi are therefore not simply discrete bilateral initiatives. They point to an Indo-Pacific strategic and economic security architecture.
