The Strait of Hormuz crisis is deepening with no end in sight as global powers adopt a wait-and-see posture in response to President Trump’s call for an international naval deployment to protect the world’s most vital oil shipping corridor. Trump posted on Truth Social claiming that many nations were already preparing to send warships, including the UK, China, France, Japan, and South Korea — but none of those countries has confirmed any such commitment. The world’s most critical oil route remains under effective Iranian control.
Iran’s blockade of the strait — launched as a retaliatory measure following US-Israeli strikes — has become the most disruptive event in the history of global oil supply. Tehran has announced that tankers bound for the US, Israel, or allied nations are legitimate military targets. Sixteen tankers have been struck since the conflict began in late February, and Iran has raised the prospect of laying mines across the waterway, making any potential naval operation there fraught with danger and risk.
The absence of European commitment is striking. France ruled out naval involvement while hostilities continued, with its defence minister drawing a firm line. President Macron’s earlier discussion of a defensive escort mission was explicitly conditioned on a reduction in fighting. The UK referenced mine-hunting drones and ongoing discussions but provided no concrete pledges. The EU’s Aspides mission has been proposed as a possible vehicle for expansion to cover the strait, but Germany’s foreign minister called the mission ineffective and expressed strong scepticism about expanding its scope in the current environment.
Japan and South Korea — deeply integrated with Gulf energy supplies — have similarly avoided firm commitments. Japan’s ruling party figure described naval deployment as legally possible but practically very challenging. South Korea pledged continued monitoring and indicated it was assessing all possible measures to protect energy security and citizens. As oil prices rise and economic pressure builds, these nations face growing urgency to either contribute to a solution or manage the consequences of prolonged disruption to their energy supply chains.
China’s response continues to be framed in diplomatic rather than military terms. Beijing is reportedly in talks with Iranian authorities about allowing oil tankers to pass through the strait safely, representing a potential diplomatic route out of the crisis. The Chinese embassy in Washington said Beijing was committed to strengthening communication with relevant parties and playing a constructive role in bringing de-escalation and peace to the region. US Energy Secretary Chris Wright said he had engaged with several countries and expected China to prove a genuinely constructive partner in restoring normal shipping conditions through the critical waterway.
