Sister cities

Twinned with Haikou

3 of 28 in this atlas

Haikou maintains twinning agreements with three cities across three different continents: Antalya in Turkey, Victoria in Seychelles, and Yangon in Myanmar. Each of these pairings is recorded as mutual, meaning both sides formally recognize the relationship rather than one city naming the other without reciprocation. The connections span coastal and island locations in differing regions of the world.
