Shares in US technology giant Apple jumped more than 3% after it signed a deal to supply its iPhone to China Mobile - the world's largest carrier.
The Chinese firm has more than 760 million subscribers and was one of three networks to be awarded China's first 4G licences earlier this month.
Apple has been looking to boost its sales in China, the world's largest smartphone market, but has struggled amid growing competition from rivals.
The BBC reports the latest deal is expected to help it increase its market share.
