Yangzijiang Shipbuilding Holdings, the China-based shipbuilder, said it is “not affected” by financial difficulties at Rickmers Maritime Singapore as ships ordered by Rickmers’ German parent haven’t been cancelled, reported Bloomberg.

“Yangzijiang is not affected by what is happening to Rickmers in Singapore as the orders to Yangzijiang are from Rickmers Holdings GmbH,” the company said in an e-mailed statement. Rickmers Holdings (corrected) holds 17.5% of Rickmers Maritime Singapore.

Rickmers Singapore’s liabilities “may cast significant doubt on the ability of the trust to continue as a going concern,” PricewaterhouseCoopers told Rickmers’ shareholders on Monday. It has existing capital commitments of US$781 million ($1 billion) and bank borrowings of US$129 million due in the next 12 months, the auditor said.

Yangzijiang said today it is building four container ships for Rickmers Holdings. Payments are up to date and the vessels are scheduled for delivery this year and next year, it said.
