Port Agreements

The Port of Los Angeles has 17 sister and friendship port agreements with ports around the world. Sister and friendship port relationships strengthen the economic and commercial bond between the respective countries, which focus on technology and operational improvements, and allow sharing components of environmental programs and policies regarding air quality, water quality and wildlife habitats to better both harbors.

A sister or friendship port agreement may also call for the sharing of various information in port infrastructure improvement, commercial facilities development, port operation and to cooperate for trade vitalization and service improvement.
The Port’s longest-standing sister port agreement is with the Port of Nagoya, established in 1959.
