European nations and Japan back efforts to secure Strait of Hormuz, ready to 'contribute'

European powers and Japan condemn Iran attacks, say ready to “contribute” to securing Strait of Hormuz

Britain, France, Germany, Italy, the Netherlands, and Japan issued a joint statement agreeing to support “appropriate efforts” to ensure safe passage through the Strait of Hormuz and to take steps to stabilise energy markets.

The countries also said they are prepared to support efforts to secure safe passage through the Strait of Hormuz and help stabilise energy markets, as the ongoing conflict continues to disrupt global shipping and energy supplies. The statement, issued by the office of UK Prime Minister Keir Starmer, expressed concern over rising tensions and threats to international trade routes.

The nations have also condemned recent attacks attributed to Iran and called on Tehran to immediately halt its actions in the region.

“We call on Iran to cease immediately its threats, laying of mines, drone and missile attacks and other attempts to block the Strait to commercial shipping,” the leaders said.

The countries warned that continued disruption to maritime traffic and global energy supply chains poses a serious risk to international peace and security. “Freedom of navigation is a fundamental principle of international law,” they added, noting that the consequences of the conflict would be felt worldwide, particularly by vulnerable populations.

The conflict has intensified in recent weeks, with reports of multiple commercial vessels being targeted. According to officials, 23 ships, including 10 oil tankers, have been involved in attacks or incidents since hostilities escalated. The situation has significantly impacted one of the world’s most critical energy corridors, which typically handles a substantial share of global oil and gas shipments.

The Strait of Hormuz remains effectively closed, raising concerns about supply disruptions and further volatility in global markets. The statement also highlighted growing alarm over the impact on seafarers, with thousands reportedly stranded on vessels in the region due to security risks.

While the six countries expressed readiness to contribute to maritime security efforts, they stopped short of committing to immediate military deployment. A UK defence official noted that the current threat level remains too high for many nations to send naval forces into the area, though coordination with allies is ongoing.

The statement also comes amid calls from Donald Trump for international cooperation to reopen the strait to commercial shipping. However, allies have indicated that while discussions are ongoing, immediate action is unlikely.

In addition to security concerns, the group backed measures aimed at stabilising global energy markets. They supported coordinated releases of strategic petroleum reserves and encouraged further steps to increase production where possible. The countries also pledged support for affected nations through international institutions as they seek to manage the economic fallout from the crisis.
