Sister cities

Twinned with Hangzhou

4 of 20 in this atlas

Hangzhou maintains formal ties with four municipalities across as many continents: Canberra, Cape Town, Curitiba, and Paramaribo. Each of these pairings is recorded here as mutual, with both cities naming the other in return. The spread runs from Oceania through southern Africa to South America, without any regional concentration or discernible pattern beyond that mutual recognition.
