Oil prices fell by almost 1 percent on Monday, with Brent crude slipping below $60 per barrel, after Chinese data showed weakening imports and exports in the world's biggest trading nation and second-largest crude oil consumer.
International Brent crude oil futures were at $59.91 per barrel at 0403 GMT, down 57 cents, or 0.9 percent from their last close, Reuters said.
U.S. West Texas Intermediate (WTI) crude futures were down 47 cents, or 0.9 percent, at $51.12 a barrel.
China's December overall exports fell by 4.4 percent from a year earlier, the biggest monthly drop in two years, official data showed on Monday, pointing to further weakening in the world’s second-largest economy. Imports last month also contracted, falling 7.6 percent, the biggest decline since July 2016.
"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.
The weak trade figures confirm a raft of indicators that have been pointing to an economic slowdown since the second half of 2018.
"Producer price inflation has decelerated for six consecutive months, adding to other signs of cooling industrial activity (in China) amid weakening global demand," rating agency Moody’s said in a note.
Traders said the data pulled down crude oil futures and Asian stock markets alike, which had both posted modest gains earlier on Monday.
