China's commerce minister says the outlook for the global economy remains grim despite it having overcome the impact of the 2008 financial crisis.
Gao Hucheng said at a G20 meeting in Shanghai that major economies must lead the way in tackling problems, including slowing trade and sluggish growth.
To boost trade the G20 ministers, from the world's major economies, agreed to cut trade costs, increase policy co-ordination and enhance financing.
