Chicago Sister Cities International (CSCI), a division of World Business Chicago (WBC), provides leadership to develop, manage, and coordinate comprehensive programs and projects with Chicago’s 29 sister cities in the areas of economic development, tourism, immigration, education, and cultural enrichment, expanding Chicago’s global reach for the benefit of the City of Chicago, its residents and businesses. Since 1960, Chicago Sister Cities International has been at the forefront of developing the international partnerships and networks that have cemented Chicago’s status as a major global city.
