China's largest shipping conglomerate China Ocean Shipping (Group) Co (COSCO Group) plans to seek a listing of its tanker fleet or inject it into its listed flagship, China COSCO Holdings Co Ltd (1919.HK) (stock code: 601919), a senior executive said on Wednesday.

The company is pushing forward with plans to list all its key assets and it still has about 50-60 billion yuan of unlisted assets, including oil tankers and ship repairing businesses, Zhang Fusheng executive vice president of COSCO Group told reporters.

"We are now restructuring the tanker fleet and will inject it into China COSCO, or seek a separate listing," he said
