China has called for an immediate halt to military operations in West Asia after escalating hostilities led to the effective closure of the Strait of Hormuz, a critical artery for global oil shipments, intensifying fears of a prolonged energy shock and wider economic disruption.Beijing’s appeal followed remarks by United States President Donald Trump urging major powers, including China, to use their influence to keep the waterway open. The diplomatic exchange unfolded as Iran moved to restrict passage through the narrow strait after coordinated airstrikes by the United States and Israel, marking a sharp escalation in tensions across the region.
China’s foreign ministry said stability in the Gulf was essential for global economic security and called on all parties to exercise restraint. Officials emphasised that the Strait of Hormuz is a vital international shipping lane and warned that prolonged disruption could undermine energy markets and trade flows worldwide. Beijing has maintained close economic ties with Gulf producers and remains one of the largest importers of crude passing through the strait.
The closure has sent shockwaves through global energy markets. The Strait of Hormuz handles roughly a fifth of the world’s oil supply, with shipments from Saudi Arabia, Iraq, the United Arab Emirates, Kuwait and other producers transiting the narrow passage. Analysts say the scale of the disruption ranks among the most severe supply shocks in years, with oil prices climbing sharply as traders priced in the risk of prolonged outages.
Energy economists note that even partial interruptions in Hormuz traffic can have outsized effects on prices due to limited spare capacity in alternative export routes. Strategic reserves in major economies offer a buffer, but sustained disruption would likely strain inventories and force governments to consider coordinated releases.
Shipping companies and insurers have reacted swiftly, with several operators suspending transit through the strait or demanding sharply higher premiums for vessels willing to enter the zone. Maritime tracking data shows a drop in tanker movements, while some cargoes have been rerouted where possible, though options remain limited given the geography of Gulf exports.
Iran’s move followed airstrikes targeting its military infrastructure, which officials in Tehran described as an act of aggression. Iranian authorities signalled that control over the strait remains a key lever in responding to external pressure, raising concerns among import-dependent economies in Asia and Europe.
Washington has defended its actions as necessary to deter further escalation, while Israel has framed its involvement as part of a broader effort to counter perceived threats. Both countries have indicated they are prepared to take additional measures if hostilities intensify, heightening the risk of a wider regional conflict.
China’s intervention reflects both its economic exposure and its broader diplomatic positioning. As the largest buyer of Gulf crude, Beijing has a direct stake in maintaining uninterrupted supply chains. At the same time, it has sought to present itself as a stabilising actor capable of engaging multiple sides, building on previous mediation efforts in the region.
Market participants are closely monitoring signals from major consuming nations, including whether coordinated responses might emerge through mechanisms such as strategic petroleum reserve releases or diplomatic initiatives aimed at de-escalation. Financial markets have already shown signs of volatility, with energy stocks rallying while broader indices face pressure from inflation concerns linked to higher fuel costs.
The disruption has also revived long-standing debates about energy security and diversification. Countries heavily reliant on Middle Eastern crude may accelerate efforts to secure alternative supplies or expand investments in renewable energy, though such shifts typically unfold over longer timeframes.
