The Boulder Cuba Sister City Organization (BOCUSCO) is a 501(c)3 non-profit, non-political, all-volunteer citizen network that exists to create lasting partnerships to promote cultural sharing, understanding, and exchange between citizens of Boulder, Colorado, and the municipality of Yateras, Guantánamo, Cuba. Yateras, a municipality located in the mountainous easternmost Cuban province of Guantánamo, became Boulder’s sixth sister city in 2002. President Eisenhower promoted a people-to-people initiative in 1956 to involve individuals in citizen diplomacy, with the hope that personal relationships, fostered through sister city, county, and state affiliations, would lessen the chance of future world conflicts. Boulder is a member of Sister Cities International and has other sister cities in Israel, Japan, Kenya, Mexico, Nicaragua, Nepal, Palestine, Tibet, and Tajikistan.
​
​Although many of our exchanges and activities involve the community of Yateras, we are also involved in projects, such as health and environmental projects in other areas of Guantánamo Province, including Baracoa and Guantánamo City.
