US President Donald Trump on Monday announced a landmark $300 billion partnership with India's Reliance Industries Limited to build America First Refining — the first major new oil refinery to be constructed in the United States in 50 years — describing the project as a historic milestone for American energy dominance and national security.

Trump made the announcement on his Truth Social platform, framing the Brownsville, Texas facility as both the largest single investment in US history and a direct strategic response to the disruption of global oil supplies through the Strait of Hormuz caused by the ongoing West Asia conflict. With Iranian strikes on Gulf energy infrastructure having severely rattled international energy markets and driven Brent crude past $100 per barrel, the announcement is a pointed signal of Washington's intent to reduce dependence on Middle Eastern oil through a dramatic expansion of domestic refining capacity.

Located at the Port of Brownsville on the Texas Gulf Coast, the refinery is expected to create thousands of American jobs and has been billed as the cleanest refinery in the world — a designation that positions the project as simultaneously advancing energy security and environmental standards. The facility is a cornerstone of Trump's America First energy agenda, which prioritises lowering taxes and streamlining regulatory permits to achieve what the administration calls "energy dominance."

For Reliance Industries — already one of the world's largest refining companies — the partnership marks a significant deepening of its footprint in the US market and signals the Mukesh Ambani-led conglomerate's ambitions in the American energy landscape at a moment of historic global supply disruption.
