Shanghai Guojin Leasing has signed an agreement to provide cash for the 2,500-teu vessels, Asian reports said.

The original 2013 order was for six vessels worth $127.4m, delivering from China’s Zhoushan Wuzhou Ship Repairing & Building Co in 2015, but the company looks to have declared four options since.

Zhonggu Shipping is a coastal liner company that was privatised in 2003. Its website says it operates around 40 vessels totalling 500,000 dwt.
