Twinned with Incheon

11 of 21 in this atlas

Incheon maintains twinning ties with municipalities across several continents, including multiple Chinese cities such as Chongqing, Dalian, Tianjin, and Wenzhou, alongside Japanese partners Kobe and Yokohama. Other pairings extend to Haiphong, Manila, Panama City, Philadelphia, and Rio de Janeiro. Every one of these relationships is recorded here as mutual, with each partner city naming Incheon in return, rather than as a one-sided declaration.
