In 1999 Dobrich signed a letter of intent and a twinning agreement with the Belarusian town of Pinsk. It is situated 180 km away from the administrative centre of the district - the city of Brest. With a population of 130,000, Pinsk is the third largest town in the region. 1997 was the 900th anniversary of the town.
A delegation from Pinsk visits Dobrich annually on 25th of September. Businesses from the two towns, operating in the food processing sector, are now considering joint ventures.
Mayor of Pinsk is Mr. Alexander Alexandrovich Gordich (elected 2005).
