Khmelnytskyi is a city of 290 000 inhabitants located in the west of Ukraine, in the historic region of Podolia, on the banks of the Boug river.

The city actively co-operates with 13 twin cities: Silistra (Bulgaria), Rustavi (Georgia), Šiauliai (Lithuania), Bălţi (Republic of Moldova), Ciechanów (Poland), Bor (Serbia), Manises (Spain), Kramfors (Sweden), Starobilsk (Ukraine), Carmel (Israel), Aguascalientes (Mexico), Modesto (United States) and Shijiazhuang (China).

Khmelnytskyi has been celebrating Europe Day since 2003, notably by organising festivals of European culture under the banner “Europe in our heart”.

To ensure co-operation with its twin cities, Khmelnytskyi created a unique project in 2020: an online platform which allows citizens to find useful information about the twinned cities and make useful contacts.
