Twinned with Busan

19 of 27 in this atlas

Busan maintains twinning ties with municipalities across a wide geographic spread, from Auckland and Manila in the Asia-Pacific region to Barcelona, Istanbul, and Saint Petersburg in Europe, Casablanca in Africa, and Chicago, Los Angeles, Montréal, Rio de Janeiro, and Tijuana across the Americas. Every pairing listed here is mutual, with each partner city naming Busan in return, forming a consistently reciprocal network rather than a one-sided arrangement.
