Since the end of the Greek embargo, Greece has become the country's most important business partner. (See Greek investments in North Macedonia.) Many Greek companies have bought former state companies in North Macedonia, such as the oil refinery Okta, the baking company Zhito Luks, a marble mine in Prilep, textile facilities in Bitola, etc., and employ 20,000 people. The moving of business to North Macedonia in the oil sector has been caused by the rise of Greece in the oil markets.
