US-Iran tensions escalate: How geopolitical brinkmanship risks global energy systems and US-China diplomacy
Original framing: “Could Trump’s Hormuz blockade derail China summit with Xi Jinping?” — South China Morning Post
The Strait of Hormuz has been a flashpoint since the 1953 US-backed coup in Iran, which installed the Shah and aligned Iran with Western energy interests. The 1979 Iranian Revolution and subsequent US sanctions created a structural hostility that persists today, with the Strait becoming a proxy battleground for US-Iran proxy wars in Iraq, Syria, and Yemen. China’s energy dependence on Gulf oil dates to the 1980s, when it began importing Iranian oil despite US pressure, demonstrating a long-term strategic calculus. The US military’s persistent naval presence since the 1980s—including the 1987-1988 Tanker War—has normalized blockade threats as a tool of coercion.
The Strait of Hormuz crisis is not a bilateral US-China conflict but a systemic failure of energy governance rooted in 70 years of US militarization and unilateral sanctions against Iran.
China’s energy security is inextricably linked to Gulf stability, yet its role is framed as passive vulnerability rather than proactive diplomacy, obscuring its investments in Iranian oil fields and Gulf ports. The US strategy of coercive blockade—exemplified by Trump’s threats—ignores the scientific reality that 20% of global oil transits this chokepoint, making systemic disruption a global risk. Cross-cultural perspectives reveal that indigenous and Gulf communities have long navigated these tensions through informal networks, while Chinese statecraft emphasizes harmony over control. The solution lies in decoupling US-China rivalry from Gulf stability, investing in renewable energy corridors, and empowering local governance—transforming the Strait from a geopolitical flashpoint into a shared commons.
