The picture

It grew from relief work after the 2004 Indian Ocean tsunami, held talks in 2007, then lapsed when Australia stepped back in 2008. Revived in 2017, it held its first leaders' summit in 2021. It is not a military alliance: work covers maritime surveillance, vaccines, critical technology, undersea cables and disaster relief, and all four navies drill together in the Malabar exercise. Foreign ministers met twice in 2025, but India's turn to host leaders stalled amid the US tariff fight.

Why it matters

It draws India, which has no US alliance, into US-backed coordination in Asia, signaling to Beijing that its neighbors can combine.

Key facts and numbers

Quad leaders' and foreign ministers' joint statements (2021–25), Malabar exercise records, and the 2007 and 2017 meeting announcements.

What to watch

Whether it survives US–India tariff tensions, and whether it would ever act together militarily; India insists it will not. As of 2026.

Connections (3)

▸India is a member of The Quad (US, Japan, India, Australia)Fact

The relationship

Border clashes with China pushed India closer to the US, Japan and Australia in the Quad, a forum on maritime security, technology, health and supply chains. India insists it is not a military alliance, and the 2025 US tariff fight stalled the leaders' summit India was due to host.

Since when and why

Grew out of 2004 tsunami relief; first met in 2007, revived in 2017, leaders' summits since 2021; foreign ministers met in New Delhi in May 2026.

How we know

Quad joint statements and meeting records; as of 2026 the leaders' summit India was to host had not been held.

What to watch

Whether Trump's Washington values the Quad as much as its predecessors did, and how far India would commit in a Taiwan crisis.

▸India–China border dispute pushed India closer to The Quad (US, Japan, India, Australia)Widely agreed

The relationship

India once kept the Quad at arm's length to avoid provoking Beijing. After the deadly 2020 Galwan clash it moved closer: it brought Australia back into the Malabar naval exercise in 2020, joined the first Quad leaders' summit in 2021 and deepened intelligence sharing with the US. Delhi still insists the Quad is not an alliance.

Since when and why

Galwan Valley, Ladakh, June 15, 2020; four-navy Malabar in November 2020; first leaders' meeting, held virtually, March 12, 2021.

How solid?

Widely agreed by analysts, who note the timing; Indian officials cite China's border conduct, though Quad statements avoid naming China.

What to watch

Debated: whether the 2024–26 India–China thaw, plus US tariff friction, cools India's enthusiasm for the Quad.

▸Japan is a member of The Quad (US, Japan, India, Australia)Fact

The relationship

Prime Minister Shinzo Abe proposed the first Quad talks in 2007 and later described a 'democratic security diamond' of the four countries around China. Tokyo backs its practical work, such as maritime surveillance and infrastructure in Southeast Asia and the Pacific, and uses it to bind India and the US into its 'Free and Open Indo-Pacific' vision.

Since when and why

First meeting in Manila, May 2007, at Abe's initiative; Tokyo hosted the 2022 leaders' summit.

How we know

Abe's speeches and his 2012 essay 'Asia's Democratic Security Diamond', plus Japanese foreign ministry records of Quad meetings.

What to watch

Whether Japan, under Takaichi, can hold the Quad together if US–India ties sour or Washington loses interest.
