Yangzijiang Shipbuilding has secured a potential 10-ship order from an unnamed Japanese shipowner for 10 containerships of 3,500 teu.

The deal brings 2020 bookings at China’s largest privately-owned shipbuilder to over $1bn, excluding options, the company said.

The latest order is for five firm boxships worth a total of $198m, plus options for a further five sisterships that could take the contract value to $396m.
