Sister Cities are partnerships between two cities from different countries that aim to promote cultural exchange, economic ties, and mutual understanding. These relationships often involve collaborative projects, educational exchanges, and shared initiatives that benefit both communities. The concept began after World War II to foster peace and friendship. Cities typically establish Sister City relationships based on shared interests, history, or cultural similarities. Programs may include student exchanges, joint business ventures, and cultural festivals. Many cities around the world participate in this initiative, enhancing global cooperation and community engagement through their Sister Cities partnerships.
