The Strait of Hormuz crisis has highlighted a significant gap in the international framework for protecting commercial shipping in active conflict zones — a gap that the current crisis is making increasingly costly and that will need to be addressed whether or not the immediate crisis is resolved. The absence of a clear legal mandate, military framework, or institutional mechanism for protecting international shipping through a contested waterway has left the world’s most critical oil route undefended and the global economy exposed to the consequences. President Trump’s ad hoc coalition appeals have only underscored the absence of an established framework that would make such a response more automatic.
Iran’s blockade of the strait began in late February as retaliation for US-Israeli airstrikes, generating the most severe oil supply disruption in history. One-fifth of global oil exports ordinarily flow through the passage. Tehran has attacked sixteen tankers and threatened to mine the waterway. Each government Trump named in his coalition appeal has had to conduct its own legal analysis, political risk assessment, and military planning from scratch — a process that takes time, produces divergent results, and has so far yielded no firm commitments from any nation.
France ruled out sending ships while fighting continued. The UK explored lower-risk drone options. Japan examined constitutional and legal constraints before concluding the threshold was very high. South Korea pledged careful multi-angle deliberation. Germany questioned the effectiveness of the EU’s existing naval framework. No government committed forces. The divergent responses reflect not just different national interests but the absence of a shared framework that would define roles, rules of engagement, legal authorities, and risk-sharing arrangements in advance — making individual decision-making faster and more predictable.
The development of such a framework — whether through NATO, the UN, a dedicated maritime security treaty, or some other mechanism — would require sustained political will and significant diplomatic investment. The Hormuz crisis may provide the impetus for such an effort if policymakers draw the right conclusions from the current failure of ad hoc coalition-building. The lessons of the crisis are clear: the world needs a standing framework for protecting critical global shipping routes that can be activated quickly when a crisis emerges, rather than having to build a coalition from zero in the middle of an active conflict.
China’s diplomatic engagement with Tehran, while addressing the immediate crisis, also has implications for the longer-term framework discussion. Beijing’s ability to engage Iran directly through bilateral diplomacy suggests that any future protective framework for the strait would need to incorporate China’s role — a significant departure from previous Western-centric approaches to maritime security. The Chinese embassy confirmed China’s commitment to constructive regional engagement. US Energy Secretary Chris Wright expressed hope that China would prove a constructive partner, a recognition that the future of Hormuz security, like its present, involves China in a central and unavoidable way.
