Hong Kong-listed Chinese energy stocks jumped Tuesday, tracking rising oil prices amid fresh conflict between the U.S., Israel, and Iran. PetroChina, CNOOC Ltd, ENN Energy, and Hong Kong and China Gas all gained between 1% and 4%, outperforming the broader Hang Seng index which fell 0.5%.

Oil prices surged as markets worried about supply disruptions through the Strait of Hormuz, which handles 20% of the world's oil. Upstream explorers like PetroChina and CNOOC led the rally since they directly benefit from higher crude prices.

China stands as Iran's largest oil consumer, with tensions potentially disrupting flows to the world's second-largest economy. The conflict may accelerate Beijing's push toward independent oil exploration, benefiting the country's largest producers. China's substantial oil reserves offer near-term protection for refiners.

Trump has suggested a prolonged conflict with Iran, while Netanyahu insists it won't be "endless war." Investors will monitor developments closely, with oil supply remaining the primary market driver.
