Sister City Association of Chattanooga, Inc. (SCA) is a group of volunteers interested in establishing meaningful and lasting global friendships through cultural, educational, institutional, and commercial exchanges.Our missions is to promote peace through mutual respect, understanding, and cooperation — one individual, one community at a time. We believe that such interaction is important in developing long-term friendships between the residents of the sister cities while underscoring regional similarities and differences.The citizens of both communities benefit from this kind of shared realization – and the outcome is usually a better world for us and future generations.
