Singapore Prime Minister Lawrence Wong and Malaysian Prime Minister Anwar Ibrahim spoke on 20 April to coordinate their countries' responses to the ongoing Middle East war, agreeing on the need for sustained diplomacy to reach a durable resolution to the crisis. The two leaders also discussed closer bilateral cooperation to strengthen supply chain resilience, with Anwar separately highlighting Malaysia's efforts to manage energy supply pressures and deepen regional electricity integration through the ASEAN Power Grid. The call comes as tensions remain high following a conflict that began on 28 February when the United States and Israel launched strikes on Iran; Iranian threats to restrict passage through the Strait of Hormuz (a narrow waterway through which a significant share of global oil supplies flow) have added urgency to regional economic contingency planning.
