Global diplomacy roundup: India, US-Nato, Strait of Hormuz in April 2026

A summary from the South China Morning Post outlines seven international relations developments from April 2026. New Delhi's Quad diplomacy faces challenges as India organizes a meeting for foreign ministers without the presence of key leaders, perceived as an attempt to address its issues. In Beijing, Russian and Chinese diplomats convene to deliberate on Iran, Ukraine, and Taiwan amidst escalating tensions with the US. The control of the Strait of Hormuz has emerged as a pivotal issue in US-Iran discussions, with President Trump transforming a previous concept into a formal proposal aimed at reconciling Tehran's aspirations for dominance with Washington's demand for free navigation. Additional reports focus on US-Nato strains and a potential Trump-Iran collaboration.
