Two shipping lines were in talks to buy as much as 40% of the project, the unlisted container terminal operator said. Deputy director Hao Yunhui told the South China Morning Post that the two shipping lines are French shipping lines CMA CGM and Taiwan's Evergreen Marine.
Construction of the berths would start at the end of next year, adding the group would hold 60% of the project.
Evergreen's Italian unit, Italia Marittima, is representing the company in the talks because Taiwan authorities ban local shipping firms from investing in Mainland ports.
Tianjin port is the Mainland's sixth biggest by throughput. Located at the heart of the Bohai Rim, it handled 2.15 million teu (20-foot equivalent units) of boxes in the first four months this year, an increase of 23.8% year on year.
