President Donald Trump’s ambitious push to assemble a multinational naval coalition to protect oil shipping through the Strait of Hormuz has produced little more than cautious language and non-committal statements from allied governments. The US leader urged the UK, China, France, Japan, South Korea, and any nation that receives oil through the waterway to send warships to the region — claiming many were already preparing to do so. In reality, not a single named country has confirmed such plans.
Iran’s blockade of the strait, launched in retaliation for US-Israeli strikes, has generated the largest recorded disruption to global oil supply. The strategic waterway normally carries about one-fifth of the world’s oil exports. Tehran has announced that any tanker bound for the US, Israel, or their allies is a legitimate war target and will be destroyed without delay. Sixteen tankers have been struck since the conflict’s outbreak in late February, and Iran has raised the possibility of mining the waterway — making it one of the most dangerous maritime corridors on the planet.
European nations have largely demurred. France’s defence minister stated definitively that no French ships would be committed to the strait while the conflict was escalating. President Macron had spoken of a future purely defensive escort mission involving European and non-European partners, but conditioned any action on a meaningful reduction in hostilities. The UK confirmed it was in discussions with allies about various options, including the deployment of mine-hunting drones, but made no commitments beyond that. The EU’s Aspides mission may be considered for expansion, though Germany’s foreign minister publicly questioned its track record of effectiveness.
In Asia, South Korea and Japan — both deeply vulnerable to oil supply shocks — have responded with measured caution. A senior Japanese lawmaker said the law did not necessarily prohibit naval deployment but described the political and security threshold as extremely high. South Korea’s foreign ministry acknowledged Trump’s call and said it was reviewing the situation, emphasising its need to protect its citizens and secure its energy supply routes. Neither country has moved toward a concrete military decision. The human and economic cost of the disruption continues to mount as global oil prices spike.
China, which depends on the strait for massive quantities of crude oil and maintains close ties with Iran, has steered well clear of any military language. Beijing’s response focused on diplomatic engagement, with the Chinese embassy affirming its intention to work constructively with regional parties toward peace. The US energy secretary said he hoped China would be a constructive partner in restoring access to the strait, noting that initial dialogue with relevant nations had been encouraging. Behind the scenes, China is reportedly in talks with Iran about permitting tankers to pass — though no definitive agreement has been reached.
