As Trump woos China, the Quad grouping drifts towards irrelevance

But as Washington courts Beijing and shifts military focus away from Asia, analysts across the region say the Quad is increasingly struggling to define its purpose.

The Tuesday meeting of the Quad is “an attempt to agree on a summit date before the grouping slides into irrelevance”, Ariga said.

Meanwhile, Beijing-based political analyst Einar Tangen said Rubio’s visit to India before the meeting was, in itself, telling.

“From Beijing’s perspective, Rubio’s trip reveals Washington’s underlying anxiety. If the Quad was fully confident and strategically aligned, reassurance would not be necessary,” he told Al Jazeera.

Tangen said Beijing interpreted the Trump-Xi summit as a diplomatic asymmetry — one that made Washington’s scramble to reassure its partners all the more transparent.

“After Trump appeared eager to stabilise relations with Beijing, Washington suddenly needed to convince its partners that America had not abandoned the Indo-Pacific,” he said.

Trump needed the appearance of engagement with Xi more than the Chinese leader needed him, Tangen said. In Beijing’s reading, China gave Trump “ceremony and symbolism”, but not the “strategic concessions” Washington was looking for, he said.

“That perception matters because it helps explain why Rubio was dispatched afterward to reassure India, Japan, and Australia that the Quad still matters and that Washington remains committed to Indo-Pacific balancing,” he said.

The Quad additionally suffers from a structural problem that goes beyond any single summit. The alliance is highly informal, with no formal treaty, no permanent secretariat and no binding mutual defence commitments.

A lack of leadership and a more disengaged Washington have ultimately eroded the Quad’s strategic coherence, argued Ariga.

“No leaders’ summit was held in 2025. Trump has never attended one, and neither has Japan’s Takaichi,” she noted, referring to Prime Minister Sanae Takaichi.

“The grouping has been essentially leaderless at the top level for over a year.”

The Quad has pursued low-risk initiatives such as vaccines, critical technologies, supply chains, and maritime domain awareness, which the Japanese analyst said are “useful at the margins, but they cannot conceal the absence of collective political will”.

“These are worthwhile, but they are second-order achievements for a grouping conceived as a strategic bulwark,” said Ariga.

The key question, one that Tuesday’s meeting will not resolve, is whether the Quad retains a coherent purpose if its leading member is simultaneously seeking accommodation with the power it was designed to counterbalance, said the Japanese analyst.

The grouping received only a single passing mention in Trump’s National Security Strategy unveiled in late 2025, she said.

“That marginalisation would have been unthinkable two years ago,” Ariga said.

Tangen said Beijing has drawn its own conclusions from this drift. For years, China viewed it as an “Asian NATO” in the making.

“Beijing’s assessment of the Quad has evolved from viewing it as a potentially unified anti-China coalition into seeing it as a structurally uneven alignment held together primarily by concern over China rather than by deep internal unity,” he said.

“China increasingly doubts whether the four countries share the same long-term strategic vision or level of commitment.”

As US forces leave Asia, fears grow within the Quad

The redeployment of US forces and warships from the Asia Pacific to the Middle East has further deepened unease within the bloc.

When Washington moved troops from Japan to the Middle East, Tokyo saw it as a removal of a direct check on Chinese power at a time when Beijing is conducting large-scale military exercises around Taiwan, said Ariga.

“The troop redeployment and the Beijing summit together create compounding perception risks,” she said.

One of Japan’s responses has been to work the phones after the Trump-Xi summit. Prime Minister Takaichi got in touch with Trump within days, the Japan analyst explained.

“The speed of that call reflects how anxiously Tokyo is monitoring every signal from Washington,” said Ariga.

Tangen said Chinese strategists view Trump’s unpredictability as an unintended strategic gift.

“He has made America’s alliance system appear conditional, negotiable, and transactional rather than permanent and values-based,” Tangen said.

Anxiety over abandonment fuels deeper Asia Pacific hedging

For Japan, the optics of the Trump-Xi summit were also alarming.

“There were some concerns within the Japanese policy community ahead of the Xi-Trump summit last week that Trump would ‘sell out’ its Asian allies by laying claim to the Western Hemisphere while leaving China to expand its military, political and economic influence in Asia,” Ariga told Al Jazeera.

“We managed to avoid that this time, but there is still a lot of anxiety in Japan about abandonment.”

Ariga said Tokyo has responded by doubling down on ramping up its own security.

“The defence budget is up 9.4 percent for fiscal 2026, hitting 2 percent of GDP two years ahead of schedule,” she said.

Tokyo has also deepened security partnerships with Australia, the Philippines and the United Kingdom through the Global Combat Air Programme (GCAP) — a fighter jet development alliance — hedging against an unpredictable Washington, said Ariga.

Beijing sees the same hedging dynamic playing out across other Quad members. Tangen said Chinese policymakers believe India, Australia and Japan are each recalculating their position.

New Delhi saw the Trump-Xi summit as evidence that Washington could ultimately negotiate directly with Beijing while “expecting India to continue absorbing regional balancing costs”, he said.

“That concern becomes sharper when combined with American engagement with Pakistan, suspicions in India regarding US political interference narratives surrounding Modi’s last election, and in the instability produced by colour revolutions in neighbouring Bangladesh and Nepal.”

These developments are reinforcing India’s instinct for strategic autonomy rather than formal bloc alignment, said Tangen.

In Australia, similar doubts are emerging for different reasons, the analyst said.

“Canberra has faced tariffs, steel disputes, pharmaceutical penalties … pressure over defence spending, and public attacks on Ambassador Kevin Rudd,” said Tangen, pointing to this as evidence from China’s perspective that Washington increasingly treats even close allies through a transactional economic lens.

“Washington simultaneously pressures allies economically while asking them to shoulder greater strategic risk against China,” he said.  “Beijing believes these differences are widening under Trump rather than narrowing.”

From China’s perspective, that is the Quad’s central vulnerability.

“China still views it as a containment structure, but increasingly sees it as one where each member is quietly calculating whether they are participating in a durable strategic coalition or merely serving as bargaining chips in Washington’s larger negotiations with Beijing,” said Tangen.
