Can the Quad stay relevant to boost Indo-Pacific security?

Foreign ministers from the US, India, Japan and Australia — collectively known as the Quad — need to put past differences behind them if the alliance is to remain an effective means of countering China. Foreign ministers from the US, India, Japan and Australia — the four nations that make up the Quadrilateral Security Dialogue, better known as the Quad — are set to meet in New Delhi over three days from Sunday to discuss Indo-Pacific security, energy supplies and emerging technologies. The meeting comes as China continues to test geopolitical and security boundaries in the region. But it's another issue, which is not on the agenda, that looms large over the gathering: how to keep the alliance alive and relevant in an ever more challenging geopolitical landscape and an increasingly assertive China. Trump's tariffs, peace claims stir tensions with Modi The Quad, which unites the four nations in seeking a Free and Open Indo-Pacific (FOIP), has not had a meeting of national leaders since 2024, when then-President Joe Biden hosted his counterparts in Wilmington, Delaware. India was meant to host the next annual meeting in the latter part of 2025, but that never materialized amid tensions between India and the new administration of President Donald Trump. Trump has imposed tariffs and punitive duties on Indian imports to the US, straining ties with Indian Prime Minister Narendra Modi. The US president further antagonized New Delhi by claiming to have mediated a settlement to border clashes between India and Pakistan in May last year. The US president was also critical of India purchasing Russian military equipment. Rubio's delicate diplomatic mission One year on, Secretary of State Marco Rubio, who is heading the US delegation to India, is tasked with smoothing ruffled diplomatic feathers. With Trump's attention apparently focused on the war in the Middle East and, potentially, Cuba, Rubio's mission could be a challenging one. "The US, Japan and Australia already had an important and effective trilateral security arrangement, but the whole purpose of the Quad was to bring India in as another power to give it more influence and reach," said James Brown, a professor of international relations at the Tokyo campus of Temple University. "Unfortunately, this US administration does not seem to have grasped that or valued India's presence as an ally, which has badly alienated Modi," he told DW.

Writing in the Foreign Policy magazine, Derek Grossman, a professor at the University of Southern California, cautioned that should Trump decline to take part in the next leaders' meeting, likely to be held in Australia around the end of 2026, "then the Quad will be relegated to geopolitical insignificance, and it may even spell the end of the grouping entirely." And the big winner in that scenario, analysts point out, would be China. "Beijing has consistently viewed the Quad with suspicion and often portrays it as an attempt at containment," said Joseph Kristanto, a maritime security analyst at Singapore's S. Rajaratnam School of International Studies. Threats to regional security "A weakened or fragmented Quad would reinforce narratives of declining US commitment, allied disunity and the limits of minilateral security cooperation in the Indo-Pacific," Kristanto told DW. "More broadly, uncertainty around the Quad could also unsettle smaller regional states seeking a stable balance of power without choosing sides." He played down, however, suggestions that the alliance is on the brink. "I don't think that recent tensions within the Quad indicate a collapse of shared interests; rather, they highlight the growing challenges in managing a partnership among four countries with distinct strategic cultures, priorities and expectations," Kristanto said.

Equally, it was not designed to operate with the rigid discipline of NATO-style institutions, with that informal and flexible structure providing a different type of resilience. The Quad has also weathered previous periods of inactivity and political hesitation that were similar to the current climate, not least when Australia, under former Prime Minister Kevin Rudd, distanced itself from the alliance out of concern that it would hurt Australian business interes
