US sanctions China’s oil sector over Iran trade: systemic energy geopolitics and global supply chain fractures exposed

The US sanctions on China’s oil sector and Iranian shippers are not merely a tool of foreign policy but a manifestation of a century-old struggle over energy dominance, where the US leverages the dollar’s reserve status to enforce compliance.

This strategy, rooted in the 1944 Bretton Woods system and the 1974 oil shock, has evolved into a form of economic warfare that destabilizes Global South economies while enriching black markets and US-aligned intermediaries. Historically, such measures have backfired—pushing Iran toward Russia and China, fostering asymmetric responses like cyberattacks, and entrenching a cycle of retaliation that undermines global stability. The marginalised voices—from Iranian laborers to Chinese tanker crews—are the true casualties, their livelihoods sacrificed to a geopolitical chess game played by elites in Washington, Beijing, and Tehran. A systemic solution requires dismantling the dollar’s energy hegemony, embedding humanitarian exemptions into sanctions regimes, and investing in local energy sovereignty to break the cycle of dependency and conflict.
