China's exports unexpectedly fell the most in two years in December, while imports also contracted, pointing to further weakness in the world's second-largest economy in 2019 and deteriorating global demand.

Adding to policymakers' worries, data on Monday also showed China posted its biggest trade surplus with the United States on record in 2018, which could prompt U.S. President Donald Trump to turn up the heat on Beijing in their bitter trade dispute.

Softening demand in China is being felt around the world, with slowing sales of goods from iPhones to automobiles, prompting warnings from the likes of Apple and from Jaguar Land Rover, which last week announced sweeping job cuts.
