Investing.com - Oil prices fell 1% on Monday in Asia after China reported weakening imports and exports in the world's second-largest crude oil consumer.
Crude Oil WTI Futures were down 1.1%, at $51.02 a barrel on the New York Mercantile Exchange by 12:37 AM ET (05:37 GMT).
Meanwhile, the global benchmark, Brent for March delivery shed 1.1% to trade at $59.83.
"Crude futures were back in the red as trading began for a fresh week in Asia, in tandem with most of the region's stock markets ... (as) China early Monday reported $351.76 billion trade surplus in dollar terms for 2018, the lowest since 2013," said energy consultant Vandana Hari of Vanda Insights in a note on Monday.
Oil futures recorded their biggest weekly gain in six months last week thanks to data showing output declines among major oil producers and a weekly fall in U.S. crude inventories. Optimism surrounding a possible resolution to the U.S.-China trade dispute also contributed to gains.
For the week, the U.S. benchmark rose about 7.6%, its biggest weekly gain since June. It rallied about 6% for the week.
