Copper heads for fifth weekly loss, aluminium awaits Trump-Putin summit
Copper headed for a fifth weekly loss on Friday as trade tensions between the United States and China rumbled on, while aluminium hit a three-month low ahead of a summit between US President Donald Trump and Russian President Vladimir Putin. Trump and Putin are due to meet in Helsinki on Monday and aluminium investors are looking for any hint that US sanctions on Rusal, the world’s second-biggest aluminium producer, will be eased or lifted.
