SEOUL, May 27 (Reuters) - Business leaders from South Korea, China and Japan have agreed to step up their trilateral cooperation in a bid to revitalise trade and stabilise supply chains, they said in a joint statement on Monday.

The joint statement said the three-way partnership had become a "more pressing task" after experiencing slowing economies in each country.

More than 200 participants from business and trade groups including South Korea's No.2 conglomerate SK Group chairman Chey Tae-won and Ren Hong-bin, a Chinese government official who heads the China Council for the Promotion of International Trade, gathered in Seoul on the sidelines of the trilateral summit between South Korea, China and Japan.
