Oil rose after four days of losses as President Donald Trump gave mixed signals on resolving the U.S.-China trade dispute.

Oil traded near a two-week high in New York amid signs of a further drop in U.S. stockpiles and ongoing concerns that political friction in the Persian Gulf could disrupt exports.

Oil retreated below $52 a barrel as data showing record U.S. crude production suggested markets may remain oversupplied despite output cuts by OPEC and its allies.

Oil headed for its largest monthly drop Nov. 30 since July as Iran signaled the Organization of Petroleum Exporting Countries won’t reduce its production target at a meeting this week.
