NEW YORK: Oil prices fell slightly on Tuesday, with Brent crude remaining near seven-month lows just below $60 a barrel because of increasing trade tensions between China and the United States.
Brent prices have lost more than 9% in the past week, with US President Donald Trump vowing to impose new tariffs on Chinese imports and China making further moves against US agricultural cargoes.
The United States also responded to a decline in China's yuan on Monday by branding China a currency manipulator, pushing Beijing to accuse the United States of causing chaos in financial markets.
US President Donald Trump on Tuesday dismissed concerns over a protracted trade war with China, as Beijing warned that Washington's decision to label it a currency manipulator would lead to chaos in financial markets.
International benchmark Brent futures fell 58 cents to $59.23 a barrel by 2:25 p.m. EDT [1825 GMT], having dipped earlier in the session to their lowest since Jan. 14 at $59.07.
West Texas Intermediate crude futures were down 78 cents a barrel at $53.92.
"As far as the oil market is concerned, there are two key questions: 1) Why should China carry on buying US crude oil? and 2) Why should China continue to adhere to the US sanctions when it comes to buying Iranian oil?" Commerzbank analyst Carsten Fritsch said in a note.
Global equities hit a two-month low and Brent fell more than 3% on Monday as traders worried the dispute between the world's two biggest oil buyers would dent demand, helping to prompt Tuesday's short-covering.
"It's difficult for oil to hold (up) when you have such moves in equities," Petromatrix analyst Olivier Jakob said.
Oil prices found little encouragement as the US government forecast that growth in the Permian basin and other shale formations would largely offset production losses from the Gulf of Mexico due to Hurricane Barry.
Crude could still find some support after the market settles on Tuesday, with a Reuters poll showing US crude oil inventories were expected to have fallen for an eighth consecutive week.
The American Petroleum Institute is set to release its weekly inventory data at 4:30 p.m. EDT (2030 GMT), with official government numbers to follow on Wednesday.
On the supply side, Iran has threatened to block all energy exports out of the Strait of Hormuz, through which a fifth of global oil traffic passes, if it is unable to sell oil as promised by a 2015 nuclear deal in exchange for curbing uranium enrichment.
Britain on Monday joined the United States in a maritime security mission in the Gulf to protect merchant vessels after Iran seized a British-flagged vessel.
