US President Trump and Chinese President Xi Jinping reached an agreement during a summit to oppose Iran's nuclear weapons development and maintain the free navigation of the Strait of Hormuz. This occurred amidst growing concerns about the prolonged Middle East conflict and the potential closure of the Strait of Hormuz, highlighting energy security as a key issue.
