Sister Ports
The Port of San Francisco currently has 10 sister port agreements with different ports all over the world. Sister port partnerships allow both parties to share policies and best practices on port planning and building, port management and operations, environmental protection measures, port safety and security, supply chain logistics, and cruise tourism. These partnerships also encourage more trade and business opportunities between the two ports by promoting the economic and commercial benefits of doing business with the sister port. Mostly, sister port relationships are a recognition of a good relationship between ports.
