US Secretary of State Marco Rubio is scheduled to meet in New Delhi with counterparts from Australia, India, and Japan as part of efforts to revive the Quadrilateral (Quad) security cooperation. The move comes after recent disagreements involving Iran and amid questions about how consistently the United States will maintain its commitments in the Indo-Pacific. The meetings also follow President Donald Trump’s state visit to China, where he reportedly described the prospect of US-China cooperation as a “G2,” a framing that concerns several allied governments. According to the sources, the Quad is viewed by China with suspicion, and some Indo-Pacific allies fear that if Washington emphasizes a closer US-China relationship, it could reduce their strategic relevance. Rubio’s engagement with Quad foreign ministers is presented as a symbolic step toward reaffirming cooperation, but the articles note that “staying power” remains unclear. The outlets link the diplomacy to broader regional calculations around China’s rise and to the state of coordination among US partners following policy divergence on issues such as Iran.
