China's crude oil and natural gas imports declined in March as the ongoing crisis in the Persian Gulf began squeezing energy flows to Asia. The drop marks a notable shift for the world's largest oil importer, which has relied on Middle Eastern suppliers for a significant share of its energy needs.

The Persian Gulf accounts for roughly half of China's crude imports. With shipping lanes under pressure and insurance premiums on Gulf-bound tankers rising sharply, Chinese refiners have struggled to secure consistent supply. TankerMap data shows elevated activity among VLCCs rerouting via alternative corridors, with some vessels diverting through the Cape of Good Hope to avoid contested waters near the Strait of Hormuz.

The supply crunch is putting pressure on Beijing's energy security strategy. Analysts expect Chinese buyers to accelerate efforts to diversify sourcing toward West Africa, Russia, and South America in the coming months, while domestic strategic reserves may be tapped to offset near-term shortfalls.
