Many mayors said they were thinking to cooperate with not only one, but multiple cities across different sectors.

Marko Selakovic, mayor of Kragujevac, Serbia: "We have a room for huge development. It might be trade, it might be joint development of innovative solutions for the benefit of the citizens. It might be bringing in different green technologies, it might be also exchange good knowledge, good expertise, good innovations. It might be academic partnership. It might be investment. So, sky is the limit."

Miroslav Markovic, mayor of Varazdin, Croatia: "Varazdin, my town is friend with Wuhan and we are now setting up friendship with Harbin. What I see in my town, I'm very pleased to see green development. So I think Ningbo's experience can be used in my town also."

Lu Sirui, Ningbo, Zhejiang Province: "Ningbo is just one of many Chinese cities embracing international exchanges. And it's happening not only in the business sector, but also across culture and education. Experts say that as China further opens up, its cooperation with the world will become more practical. And it will create more mutually beneficial relationships."
