Online freight forwarder iContainers has warned that new container shipping alliances are unlikely to boost competitiveness between the US and its NAFTA partners.

According to US government figures, the value of US-NAFTA goods carried by ships in 2016 fell 20% year-on-year.

Trucks take the lion's share of trade between the US, Canada and Mexico.

“The new shipping alliances are unlikely to increase the US-NAFTA ocean freight competitiveness as this is not a trade that will hold a lot of focus for them,” said Klaus Lysdal, vice president of sales and operations at iContainers.
