SINGAPORE: It may not have quite dissipated like the “sea foam” it was once dismissed as by China, but the Quad is at best idling on the high seas. The last time leaders of the Quadrilateral Security Dialogue – India, Australia, Japan and the United States – met was in September 2024. A 2025 summit in India never materialised and there is still no sign of a top-level meeting taking place this year. Instead, the four foreign ministers will be meeting in New Delhi in late May.
