Iran Says U.S. Rejected Peace Proposal; Signals Conditional Access to Strait of Hormuz

Tensions between the United States and Iran entered a complex diplomatic phase on May 15, as Tehran announced that Washington had rejected a 14-point proposal intended to end the current 40-day conflict. The Iranian plan reportedly suggested a two-stage process: an immediate halt to the war on all fronts followed by the initiation of nuclear negotiations. Iranian state media characterized the rejection as a sign of Washington's "coercive stance," signaling a potential narrowing of diplomatic channels between the Trump administration and the Islamic Republic. Simultaneously, Iranian Foreign Minister Abbas Araghchi sought to clarify the status of the Strait of Hormuz, a critical global energy chokepoint. While asserting that the Strait is "not closed," Araghchi emphasized that guarantee of safe passage for commercial vessels is inextricably linked to a "complete cessation of hostilities." Analysts suggest this indicates Iran is using maritime access as political leverage to pressure the U.S. into a ceasefire while attempting to reassure "friendly" non-Western nations and shipping interests. On the regional stage, Iran is intensifying its diplomatic messaging to the Global South. During meetings with Malaysian officials, Araghchi argued that the recent conflict demonstrates regional states can no longer rely on the U.S. or Israel for security. Meanwhile, global markets remain on edge; although ceasefire hopes initially caused oil prices to ease, the lingering risk of disruption in the Strait of Hormuz has kept Brent crude prices above the $100 mark. In Beijing, President Trump and President Xi Jinping reportedly discussed the regional instability, highlighting the role of major-power diplomacy in managing the ongoing crisis.
