“I’m delighted to sign this agreement today, strengthening Sydney’s relationship with the city and the people of Chicago,” said Lord Mayor Moore. “Our cities share much in common, including our commitments to pursuing design excellence in architecture and public art, and taking strong action on climate change.”

The agreement will further traditional links of friendship between Chicago and Sydney, and reaffirm their mutual aspiration to work in unison for the benefit of their cities and nations. The two cities will work together on the basis of friendly cooperation, equality and mutual benefit, with reciprocal cooperation as it relates to economic development, education, environment, healthcare, technology, arts and culture, tourism, and urban development.

Chicago has the largest sister city program in the U.S. The City’s sister city relationships are managed by Chicago Sister Cities International (CSCI), an initiative of World Business Chicago. CSCI has an extensive network of volunteers who work to deepen Chicago’s sister city relationships by working on programs, exchanges, and initiatives between Chicago and its sister cities.

“We are honored to welcome Sydney to the Chicago Sister Cities International network,” said Leroy Allala, Executive Director of Chicago Sister Cities International. “This new sister city relationship will further strengthen Chicago’s bond with Australia, and we look forward to working with Sydney into the future.”

“I warmly welcome this new sister city relationship between Chicago and Sydney,” said Ambassador Peter Heyward, Australian Consul-General in Chicago. “It will provide a platform for strengthening and expanding not only business links but collaboration in all sectors between two vibrant and productive communities, reflecting the unique bond between Australians and Americans we celebrate as ‘mateship.’”
