Oil slipped to around $60 a barrel today after data showed weakening imports and exports in China, the world's second-largest oil consumer, raising the prospect of a slowdown in fuel demand.
China's exports fell by the most in two years in December while imports contracted, pointing to further weakness in what is also the world's second-largest economy.
Brent crude, the international benchmark, fell 46 cents to $60.02 a barrel this afternoon, trading as low as $59.27 intraday. US crude slipped 52 cents to $51.07.
Crude gave up an earlier gain following the release today of the Chinese figures, the latest to point to an economic slowdown since the second half of 2018.
Asian and European stock markets also slipped.
But despite concern about the outlook, there is little sign that Chinese oil demand has weakened yet.
China's crude imports in December surged nearly 30% from a year earlier, Reuters calculations of customs data showed.
Oil is drawing support from supply cuts led by the Organization of the Petroleum Exporting Countries and non-OPEC allies, including Russia.
The group of producers, known as OPEC+, agreed in December to cut oil output by 1.2 million barrels per day starting in January to prevent a supply glut and boost prices.
With the rise in Brent from a dip below $50 in December, OPEC officials appear more confident that prices will be supported by output declines in January as producers implement the deal.
Saudi Energy Minister Khalid al-Falih said on Sunday the oil market was "on the right track" and there was no need for an extraordinary OPEC meeting before its next planned gathering in April.
