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 28 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.
