Twinned with Hanoi
12 of 19 in this atlas
Hanoi's twinning ties, as recorded in this atlas, span capitals and other municipalities across Asia, Europe, Africa, and North America, from Ankara and Astana to Yokohama and Montréal. Most pairings are mutual, including Beijing, Seoul, Bangkok, Jakarta, and Warsaw, while a smaller set, Kyiv, Phnom Penh, and Victoria, are declared only from Hanoi's side, not reciprocated in return.
