The shipyard assets of Hong Kong-listed China Huarong Energy are being sold to a bondholder as the company exits the shipbuilding sector.

The former China Rongsheng Heavy Industries said an unnamed bondholder has agreed to take over the "non-performing and debt-burdened" yard and engineering business.

Both parties have struck a deal to release all debts on completion.

China Huarong will then focus on the energy exploration and production sector.

Rongsheng was forced to restructure in 2016 under $2.56bn of debt in a tough shipbuilding market.

It once claimed to be China's largest shipbuilder.
