Long lines have formed at gas stations across China this week as drivers rush to fill their tanks ahead of major fuel price increases, with residents from Hong Kong even crossing the border to try to secure cheaper gasoline.
The surge in demand followed an official announcement from Beijing that fuel prices would rise beginning Tuesday. China regulates gasoline prices through a system that sets minimum and maximum retail prices. This week the government increased the ceiling for gasoline prices by more than $100 per metric ton, marking the largest increase in four years.
Because Chinese regulations require gas stations to sell existing fuel inventories before implementing new price levels, motorists had only a short window to purchase fuel at the lower price before the increase took effect.
The announcement triggered long lines at gas stations as drivers attempted to fill up before prices rose.
Some Hong Kong residents even traveled across the border into mainland China to buy gasoline, hoping to take advantage of lower mainland fuel prices.
Fuel in Hong Kong typically costs about three times more than on the mainland, making cross-border purchases appealing despite the time spent waiting in line.
However, many drivers reported frustration after discovering that some gas stations in Guangzhou had already run out of regular gasoline, leaving only premium fuel available or running out entirely due to the sudden demand.
Chinese social media platforms quickly filled with posts from Hong Kong drivers describing the long wait times and shortages.
Hong Kong drivers have also faced significant fuel price increases this year. Combined with an earlier increase in February, gasoline prices on the island have risen by as much as 50 percent in 2026.
Commercial vehicles in Hong Kong are prohibited from crossing the border to purchase fuel, but private vehicles are allowed to do so.
Ringo Lee Yiu-pui of the Hong Kong China Automobile Association warned that the rising cost of diesel fuel could create serious economic consequences.
Lee said higher fuel prices could increase shipping costs and drive up public transportation fares unless mainland authorities reconsider the tariffs applied to fuel deliveries into Hong Kong.
The price disparity has also encouraged some truck drivers to attempt to bypass restrictions by illegally transporting fuel across the border.
Hong Kong customs officials say they have already intercepted several vehicles modified with enlarged fuel tanks designed to smuggle additional gasoline.
“In the past few weeks, we have uncovered many such cases involving cars that had enlarged their fuel tank capacity and made other modifications,” customs commissioner Chan Tsz-tat said.
Authorities said the vehicles involved in those operations have been seized and may be permanently confiscated through court proceedings.
Officials warn that rising prices could also drive motorists toward black-market fuel suppliers, which poses serious safety risks.
“When this untaxed petrol is being filled into vehicles, there is an extremely high risk of fire,” Chan said, noting that illegal fuel handling could endanger both drivers and surrounding communities.
Industry analysts say higher fuel costs are already reducing profit margins for truck drivers and logistics companies, who may soon have to pass the added costs on to consumers.
