Cosco says it may sell up to a 15.1% stake in Overseas Orient (International) Ltd as part of its takeover to keep the company listed on the Hong Kong Stock exchange.

In a regulatory filing, Cosco, which announced a $6.3bn takover of the parent of Overseas Orient Container Line last July, says it may sell a piece of OOIL to entities linked to port operator CK Hutchinson, China's State Development & Investment Corp, and China's Silk Road Fund.
