Ukrainians and Serbians can now travel to each other\'s country for 30 days without a visa after an agreement between the two countries came into effect Thursday, according to the Foreign Ministry. Under the agreement, signed here in May during Serbian Foreign Minister Vuk Jeremic\'s visit, the only travel documents necessary for citizens of the two countries are passports and travel documents for children. The visa-free regime is aimed at contributing to the development of tourism and bilateral relations between the countries. Ukrainians can travel without a visa and with visa upon arrival to about 85 countries, in particular Argentina, Israel, Macedonia, and countries from the former Soviet Union.
