Canada, Japan, and European allies are in an effort to reopen the Strait of Hormuz.

Amidst the severe impact on global energy supply due to the ongoing war in the Middle East, Canada, Japan, and European allies have expressed their willingness to support efforts to reopen the Strait of Hormuz. In response to an Israeli attack targeting facilities in Iran's South Pars natural gas field, Iran launched a series of attacks on Qatar's Ras Laffan liquefied petroleum gas facility and several other locations in the region.

As a result, Britain, France, Germany, Italy, the Netherlands, Canada, and Japan jointly issued a special statement strongly condemning Iran's actions and its closure of the Strait of Hormuz.

These countries, pointing out that this situation severely impacts vulnerable populations worldwide, emphasize their readiness to take appropriate steps to ensure safe vessel traffic through the strait. However, they have not yet reached a specific agreement regarding the deployment of warships or troops, and the International Maritime Organization, a United Nations agency, has also highlighted the need to create a safe maritime corridor. Following the commencement of military action against Iran by the United States and Israel on February 28, traffic in the Strait of Hormuz, through which about 20% of the world's crude oil supply is transported, has almost completely ceased. As a result, natural gas prices in Europe have risen by about 25%, and the price of international Brent crude oil per barrel rose to US$119 before showing a slight decrease to US$103.

Although British Prime Minister Keir Starmer had previously refused to participate in such an operation, a team of British military planners has now been sent to Washington to discuss options for resuming ship traffic. He emphasized the need to end the war quickly to reduce the cost of living. Meanwhile, Canadian Defense Minister David McGuinty stated that if countries in the Middle East and Gulf region require support, Canada is also considering it in conjunction with NATO allies. NATO Secretary General Mark Rutte also mentioned that the strait cannot remain closed any longer and that strong discussions are underway with the United States to open it urgently.

US President Donald Trump has strongly criticized the insufficient support received from allied countries, especially NATO. During a discussion in Washington with Japanese Prime Minister Sanae Takaichi, he stated that he expects greater contributions from Japan, but she did not express direct agreement, focusing only on the severe impact on the global economy. Meanwhile, Canadian Foreign Minister Anita Anand stated at a conference in London that, according to Prime Minister Mark Carney's vision, Canada should take the lead with other like-minded countries in the face of current global instability.
