US Secretary of State Marco Rubio is set to begin a four-day official visit to India from May 23 to May 26 amid growing concerns over strained bilateral ties, trade tensions and shifting geopolitical equations in the Indo-Pacific region.

The high-level diplomatic engagement comes at a sensitive moment for the relationship between India and United States, which has faced turbulence over the past year following tariff disputes, energy disagreements and uncertainty surrounding American strategic commitments in Asia.

The visit is expected to focus heavily on trade, defence cooperation, energy security and the future of the Quadrilateral Security Dialogue, commonly known as the Quad.

Relations between New Delhi and Washington came under pressure after US President Donald Trump imposed steep tariffs on Indian imports last year, including additional penalties linked to India’s continued purchase of Russian crude oil. The measures triggered concern within Indian policy circles regarding the reliability of American strategic commitments.

Writing for the Council on Foreign Relations, foreign policy analyst Sadanand Dhume noted that India’s foreign policy establishment is now “more wary of the United States than at any other time this century.”

Rubio’s visit is widely being viewed as an effort to stabilise the partnership and reinforce Washington’s Indo-Pacific strategy at a time when China’s regional influence continues to expand.

A major focus of the trip will be the Quad foreign ministers’ meeting scheduled in India on May 26. The grouping — which also includes Japan and Australia — has been considered a central pillar of efforts to counter China’s growing military and maritime presence in the region.

However, concerns emerged after the cancellation of a planned Quad leaders’ summit last year and the grouping’s relatively limited visibility in the latest US national security strategy document.

Energy security is also expected to dominate Rubio’s discussions. Ongoing instability near the Strait of Hormuz has disrupted global oil supply chains and increased pressure on major energy-importing countries like India.

Before departing for Asia, Rubio said the United States was prepared to significantly expand energy exports to India. He also announced plans involving greater Venezuelan oil flows to India as part of broader efforts to stabilise energy markets and reduce dependence on Russian supplies.

Meanwhile, the US Embassy has launched a major public diplomacy campaign ahead of Rubio’s visit, including branding thousands of auto-rickshaws with American-themed visuals linked to the upcoming 250th anniversary of US independence.

Despite renewed engagement, analysts believe India remains cautious about entering deeper formal alignments and continues balancing ties through forums such as BRICS while maintaining strategic autonomy in foreign policy decisions.

Rubio is expected to hold meetings with senior Indian leadership during his visit, including discussions on defence, trade, technology, regional security and economic cooperation.
