Yangzijiang Shipbuilding has struck a deal with an Asian liner company for up to four panamax container ship newbuildings worth around $240m.

Shipbuilding sources said Regional Container Lines (RCL) has contracted the Singapore-listed Chinese shipyard to build two 4,400-teu ships, with an option for two more vessels.

“The newbuildings were the ones that RCL announced in March,” said one shipbuilding player.
