Marco Rubio's upcoming India visit is structured as a commercial mission, not a diplomatic one. He will hold talks in Mumbai with External Affairs Minister Jaishankar, then tour Reliance Industries' Jamnagar refinery — the world's largest single-site facility — and attend a reception hosted by the Ambani family. New Delhi, seat of government and customary venue for visiting secretaries of state, is not on the itinerary. No official reason has been given. The diplomatic breach became a political storm when US Ambassador Sergio Gor told the Bloomberg New Economy Forum that Washington 'expected' Jaishankar to travel from New Delhi to Mumbai to meet Rubio. Opposition leader Rahul Gandhi wrote that Rubio had 'summoned his employee.' Congress MP Pawan Khera called it 'a new low, even by the Modi Government's standards.' The Indian government offered no rebuttal, saying only that details would come 'at the appropriate time.' The Jamnagar stop tells the real story. Reliance is the biggest buyer of Venezuelan crude outside the US — significant because Washington has effectively controlled Venezuela's oil output since seizing President Maduro in January. Reliance is also investing in a new Texas refinery Trump hailed as a $300bn deal. With US midterm elections approaching and fuel prices biting domestically, Rubio's visit functions as oil diplomacy wrapped in a bilateral meeting. The broader US-India relationship is under visible strain. After trade talks collapsed last August, Washington imposed 50 percent tariffs on most Indian goods, later reduced to 18 percent under a February framework. Negotiations have since stalled — Finance Minister Sitharaman said talks had 'plateaued,' while Trade Minister Goyal said India would not sign until its exporters had an edge over Bangladesh, Vietnam, and Indonesia. The US Labor Department suspended eight companies from a green card labor certification scheme, including Indian IT giants Infosys, TCS, Wipro, and HCL. The Russia dimension compounds everything. India remains one of the world's largest buyers of Russian oil. Trump signed the Lindsey O Graham Sanctioning Russia and Iran Act last month, threatening tariffs of up to 100 percent on the five biggest importers of Russian oil or gas. On Friday, Trump signed an executive order seeking to waive those sanctions — trying to keep oil prices down before November 3 elections. India had warned Washington that new tariffs could damage bilateral ties. Carnegie's Sameer Lalwani captures the paradox: Indian public opinion of the US has hit a record low, driven by US engagement with Pakistan and the US-Israel war on Iran pushing India back toward Russian oil. Yet defence and technology cooperation has quietly deepened, and bilateral trade grew nearly 12 percent in 2025 to $240bn. 'Perceptions of the political relationship have deteriorated faster than its strategic foundations,' he wrote. The optics matter precisely because they reveal what the substance already suggested. Washington is treating India less as a strategic equal and more as a market to discipline — buy our Venezuelan oil, host our refineries, accept our tariff terms. The Mumbai meeting isn't a scheduling quirk. It's a statement about who sets the terms.
