Japan PM warns Strait of Hormuz closure inflicts 'enormous impact' on Indo-Pacific security

Japan Prime Minister Sanae Takaichi has warned that the effective closure of the Strait of Hormuz is inflicting an enormous impact on the Indo-Pacific region. Speaking on Monday during a visit to Australia, Takaichi highlighted that shipping disruptions stemming from the United States-Israeli war on Iran have severely constrained maritime traffic through the strait. The Prime Minister noted that roughly one-fifth of the world's oil and liquefied natural gas supplies normally pass through this chokepoint, with eighty percent of that volume destined for Asia.

The severity of the situation was underscored by the fact that shipping has been essentially blocked since the conflict began on February 28. While the International Energy Agency confirms the scale of the flow through the strait, the current blockade has left the region vulnerable to supply shocks. Takaichi stated that the closure has been inflicting an enormous impact on the Indo-Pacific, necessitating a coordinated response from regional partners to mitigate the economic and security fallout.

Amidst these concerns, Takaichi and Australian Prime Minister Anthony Albanese signed a series of agreements to boost cooperation on energy, critical minerals, defence, and the economy. Both nations emphasised the need for urgent communication to address the crisis, acknowledging that Australia provides approximately one-third of Japan's energy supplies and serves as the country's largest market for liquefied natural gas. Australian Prime Minister Albanese echoed these sentiments, stating that Canberra shares deep concern regarding disruptions to the supply of liquid fuels and refined petroleum products.

The diplomatic engagement resulted in concrete financial commitments aimed at stabilising long-term supply chains. Australia has announced plans to provide support of up to $1.3 billion Australian dollars for critical mineral projects involving Japanese entities. These resources target materials such as gallium, nickel, graphite, rare earths, and fluorite, which are essential for semiconductors, electric vehicle batteries, and weapons systems. Japan's government expressed eagerness to ensure a stable supply of these critical minerals, viewing them as vital for both civilian and defence applications.

This energy and minerals agreement builds upon existing defence ties between the two nations, which have ramped up in recent years amid shared concerns about shifts in the regional security environment. Last month, Canberra and Tokyo announced a separate deal worth $10 billion Australian dollars for Japan to supply Mogami-class stealth warships to the Australian navy. The combination of these defence and economic arrangements reflects a broader strategy to shore up security and supply resilience in the face of geopolitical volatility.

The joint statements issued on the first day of Takaichi's three-day visit to Australia promised continued collaboration to navigate the current crisis. Both leaders affirmed that Japan and Australia will closely communicate with each other in responding with a sense of urgency to the closure of the Strait of Hormuz. As the region grapples with the physical constraints on global oil inventories, the focus remains on maintaining open lines of dialogue to prevent further escalation of the supply squeeze.
