Shanghai International Port Group Co Ltd is seeking a stake in the Port of Hamburg, the world's largest free port, German newspaper Hamburger Abendblatt reported on Wednesday.

The report said SIPG had also expressed interest in the Port of Bremen, another of Europe's largest ports.

SIPG Chairman Chen Xuyuan said that close cooperation between his company and either of the European ports would be lucrative and all parties involved would benefit. Chen made the comment during a port conference in Hamburg.
