China has dialled back on planned fuel price hikes in a bid to reduce the burden on drivers, as energy costs surge amid the Iran war.

The local price of petrol has jumped by about 20% since the start of the conflict, which has seen Iran effectively close one of the world's busiest oil shipping channels, the Strait of Hormuz.

Gasoline and diesel prices were initially set to rise by 2,205 yuan (£239; $320) and 2,120 yuan per tonne respectively – but after government adjustments, the increases will be nearly halved to 1,160 yuan and 1,115 yuan, starting Tuesday.

More than 300 million people in China drive cars that run on petrol or diesel, with Gulf countries a major source of the country's oil.

Long queues of cars had formed outside petrol stations in multiple Chinese cities over the weekend, with some stations having to post notices that they had run out of fuel.

The latest price hike was the country's fifth and largest of the year so far - even with the reduction.

On Tuesday, the price of Brent crude oil jumped above $100 a barrel - a day after prices plunged, as conflicting accounts of potential talks between US and Iran emerged.

Beijing has over the years taken advantage of lower crude prices and the abundance of supply from Gulf states to build one of the world's biggest oil reserves, Ole Hansen, Saxo Bank's head of commodity strategy, told the BBC last week.

Despite its reserves, Beijing has shown signs of caution to manage its supplies in the short-term. Authorities in China reportedly ordered its oil refineries to temporarily cease fuel exports, in an attempt to keep domestic prices under control. China's government did not respond to BBC queries on the matter.

Barrels from Saudi Arabia and Iran account for more than 10% of its imports each, according to the US Energy Information Administration (EIA).

Other countries across Asia have also implemented a range of cost-cutting measures to help cushion the blow of soaring global energy prices. Government employees in the Philippines have been ordered to work four days a week, and public transport protests are occurring in response to rising fuel prices.

With the global energy market in turmoil, countries like Japan and South Korea, heavily reliant on oil passing through the Strait of Hormuz, are also feeling the effects, with gasoline prices approaching record highs.
