Container lines are facing further rate turbulence as the halting of a 2M alliance service marked the "first casualty" in a transpacific trade war, according to Alphaliner.

2M partners Maersk Line and MSC are suspending their Eagle service until further notice from July.

It calls at Kaohsiung, Yantian, Xiamen, Shanghai, Busan, Vancouver, Seattle and Yokohama.

The loop is the smallest of the five Far East-US west coast services operated by 2M, using six ships of between 4,200 teu and 5,000 teu.
