At Hyderabad House in New Delhi, Penny Wong, S. Jaishankar, Toshimitsu Motegi and
Marco Rubio stood shoulder-to-shoulder after the third Quad foreign ministers’ gathering since September 2024, announcing the grouping’s first joint infrastructure project: a port in Fiji. The timing carried its own message. The Quad arrived at the meeting after losing momentum when leaders failed to hold a summit last year, while Beijing had already spent months demonstrating how much leverage sits inside a minerals export licence. China cut Japan off from several heavy rare earths and other materials for at least four months, and exports of dysprosium, terbium, yttrium oxide and gallium to Japan largely stopped since December. By the time the ministers left New Delhi, ports, shipping lanes and critical minerals had collapsed into a single strategic problem.Rubio framed the Fiji project as a response to “insufficient port capacity in the Pacific Islands”, but the port announcement sat beside a new Indo-Pacific Energy Security initiative and a critical minerals framework. The sequence mattered. A bloc that once marketed itself primarily through diplomatic signalling now talks in the language of logistics, refining capacity and maritime throughput. The minerals framework will coordinate investment in mining, processing and recycling, linking industrial policy directly to security policy in a way the Quad had previously approached only indirectly through declarations about a “free and open Indo-Pacific.”
Japan pushed that evolution. Japan remains the largest rare earth magnet maker ou
tside China, yet it remains overwhelmingly dependent on Beijing for heavy ra
re earth imports and gallium. The vulnerability no longer exists in theory. Shin-Etsu stopped accepting new orders for dysprosium-containing magnets after Chinese exports tightened. Aerospace manufacturers, semiconductor producers and defence contractors all consume the same constrained materials. Once export flows slowed, inventory management became geopolitical exposure.Beijing’s leverage rests not only on mineral reserves but on industrial structure. China’s grip over gallium supply chains is rooted in its dominance of aluminum production, while its aluminum expansion over two decades created the scale and technical capacity to mass-produce gallium. Gallium itself sits inside a relatively small market where limited supply variations create outsized impacts on global availability. That makes pricing power unusually concentrated. Minor supply adjustments allow Beijing to manipulate market forces by releasing or withholding flows, turning commodity logistics into a diplomatic instrument that reaches far beyond mining.
The Quad ministers arrived in New Delhi already carrying the institutional memory of an earlier shock. China’s 2010 restrictions on rare earth exports exposed the vulnerability of Japan’s industrial base and national security. Fifteen years later, the international environment surrounding critical minerals has grown more complex and geopolitically fraught. Japanese strategists no longer describe supply disruptions as improbable contingencies. Eiki Tagami argued that Japan’s strength lay in recognising earlier than most countries that supply-chain disruptions were “very real possibilities”. The Quad’s new minerals framework effectively internationalises that Japanese lesson.
That shift alters the economic geography of the Pacific. Fiji now m
atters not merely as an island state but as infrastructure positioned
along maritime routes connecting the Indian and Pacific Oceans. The Quad has already pledged US$50 billion in Indo-Pacific infrastructure investment by 2027, while partners committed more than US$140 million to secure undersea cable networks in the South Pacific. Ports, cables and surveillance systems increasingly form one integrated architecture. The Quad partners also launched the Indo-Pacific Maritime Surveillance Collaboration, and they are developing a comprehensive Common Operating Picture for maritime awareness. Commercial infrastructure and maritime monitoring now advance together rather than separately.China understood the signal immediately. Beijing criticised the Quad as a Cold War-style grouping aimed at containing its development, while its foreign ministry said cooperation between countries should not target third parties. Yet the Quad communiqué had already sharpened its language. The four countries declared themselves “seriously concerned” about the East China Sea, the South China Sea and the “militarisation of disputed features”. Those concerns intersect directly with energy flows and shipping insurance. The ministers condemned attacks on commercial shipping in the Middle East and opposed tolls that threatened uninterrupted commerce through the Strait of Hormuz and the Red Sea. A grouping initially built around balancing Chinese influence increasingly behaves like an alliance protecting maritime trade arteries from the Persian Gulf to the western Pacific.
That expansion carries domestic political consequences inside the Quad itself. India’s participation remains strategically valuable prec
isely because it is not fully aligned with Washington. India continues to have ter
ritorial disputes with China, but Modi also signalled a willingness to improve ties with Beijing amid tensions with Trump. The failed leaders’ summit exposed those fractures. The Quad lost momentum after tensions emerged between Trump and Modi over tariffs and other matters, and analysts questioned whether the absence of leader-level engagement had downgraded the grouping’s importance. Ministerial coordination filled the vacuum because the machinery beneath the summitry never stopped moving.That machinery increasingly rewards countries able to supply infrastructure, logistics and industrial processing capacity rather than rhetorical alignment alone. The Quad Fellowship for Ports and Freight focuses on resilient port infrastructure, while India hosted a regional ports and transportation conference in Mumbai in May 2025 to mobilise maritime investment across the Indo-Pacific. Governments once measured influence through naval deployments and treaty language. They now measure it through dredging contracts, minerals recycling, shipping resilience and surveillance interoperability.
The imbalance inside that competition remains stark. China’s defence budget surpassed US$300 billion in 2023, more than four times Japan’s allocation, even after Tokyo expanded defence spending above JPY 6 trillion in
2023 and public defence spending reached JPY 7.7 trillion in 2
024. Japan’s response increasingly blends military spending with industrial resilience because the two can no longer be separated. Semiconductor production, aerospace manufacturing and naval procurement all rely on the same constrained mineral supply chains.Yet the Quad’s own structure exposes a contradiction. The grouping gains urgency every time Beijing weaponises supply chains, but China’s pressure simultaneously deepens dependence on the very industrial systems the Quad struggles to replicate. Implementation gaps persist between Quad financial commitments and on-the-ground execution. Resource allocation constraints in India and Australia hamper sustained engagement, while differing regulatory systems complicate coordination. Beijing does not need to match every infrastructure pledge if it already controls the processing layers beneath the technologies those projects require.
That leaves the Indo-Pacific entering a phase where strategic influence depends less on formal alliances than on who controls industrial choke points embedded deep inside civilian commerce. The Quad ministers came to New Delhi seeking to prove relevance after a year of doubts over summit diplomacy. They left having tied the credibility of the grouping to ports in Fiji, rare earth processing, maritime surveillance networks and shipping corridors stretching from the South China Sea to Hormuz. Beijing has spent years building leverage through supply concentration. The Quad is now trying to build leverage through coordination.
