Three-month copper on the London Metal Exchange gained 0.4 percent at $9,230.50 a tonne by 0100 GMT, after sliding to $9,115 in the previous session, its lowest since late December. It was on course for a 6.3 percent weekly loss, the biggest since early June last year.
Shanghai's most active copper futures contract also edged up 0.4 percent at 69,530 yuan.

might spread to major oil exporters like Saudi Arabia and Iran.
