Shippers are concerned that the P3 Alliance of Maersk Line, CMA CGM, and MSC could end up hurting competition and pushing their costs up, Chris Welsh, secretary general of the Global Shippers Forum (GSF), told industry news site ShippingWatch.

Citing a recent meeting with a shipper, Welsh said companies that work with the container carrier lines do not yet know how the alliance could affect their contracts.

“They don’t know which routes will be affected, which services, and they’re about to start renegotiating their contracts now,” he said.
