Boston currently has ten Sister Cities from Hangzhou to Praia, and continues to foster international exchanges. The purpose of these exchanges is to create international understanding and goodwill.

A Sister City agreement is formalized when two communities from different nations join together to develop a friendly and meaningful relationship. The two cities exchange people, ideas, culture, education, and technology. Citizens from both communities learn about each other's culture and become directly involved in developing unique solutions to common problems.

The Sister Cities Program promotes world peace in an individual level and encourages citizens to better understand community, by contrasting their way of life with another culture. Find out more about the Sister Cities program.
