US Secretary of State Marco Rubio met Adani Group Chairman Gautam Adani and Tata Sons Chairman N Chandrasekaran in Mumbai on October 21, 2026, before travelling to Jamnagar, Gujarat, to visit Reliance Industries’ oil-refining complex and other facilities. The meetings brought the US official into contact with leaders of three of India’s largest business groups as energy, manufacturing and technology cooperation remain important areas of India-US engagement.
Rubio arrived in Mumbai on Tuesday afternoon. On Wednesday morning, he first met Gautam Adani and later held a meeting with N Chandrasekaran. Neither side publicly disclosed details of the discussions.
Adani and Tata’s Expanding Industrial Interests
The Adani Group has businesses across ports, airports, energy, logistics and infrastructure. It has also expanded its focus on renewable energy and manufacturing, areas linked to India’s efforts to strengthen domestic supply chains and attract international investment.
Tata Sons, led by Chandrasekaran, oversees businesses spanning automobiles, steel, information technology, aviation, electronics and advanced manufacturing. The Tata Group has been investing in areas such as semiconductors and battery technology as India seeks to expand its role in global manufacturing and technology supply chains.
Reliance Jamnagar Visit Focuses on Energy
After the Mumbai meetings, Rubio travelled to Jamnagar to visit Reliance Industries’ integrated industrial complex. The facility houses the world’s largest single-site oil refinery, with a combined processing capacity of around 1.4 million barrels per day.
His itinerary also included Vantara, Reliance’s wildlife rescue and rehabilitation initiative, and the company’s planned new-energy manufacturing facilities. The giga complex is designed to house manufacturing units for solar modules, battery energy storage, green hydrogen electrolysers, fuel cells and power electronics.
Energy Security and India-US Business Ties
Energy security is a key context for Rubio’s visit. The United States has been exploring ways to expand markets for Venezuelan crude, while India continues to manage its energy sourcing and supply needs. Reliance’s ability to process different grades of crude makes its Jamnagar refinery relevant to these discussions.
The wider engagement also reflects opportunities for cooperation in clean-energy manufacturing, technology, infrastructure and industrial investment. However, the meetings with Adani and Tata leaders did not result in any publicly announced agreements. Any future commercial outcomes will depend on further discussions between the companies and their potential US partners.
