"Hungarian Foreign Ministry informed our embassy about an event on Oct. 13 titled "Self-determination for Zakarpattia." What is it? Does Budapest support separatism?" the head of the Foreign Ministry said.
"We have sent an immediate protest note with a demand to ban this provocation! We are certain Hungary will continue respecting Ukraine's territorial integrity," Klimkin wrote.
On Oct. 5, Ukraine's parliament adopted Education Act of Ukraine providing that education in schools can be held in the languages of ethnic minorities up to 4th grade. From the 5th grade up, school students are obliged to take all classes in Ukrainian, the only state language in Ukraine. The provision sparked criticism by Budapest, which threatened to block Ukraine decisions in the EU over the language provision. On Sept. 25, President Poroshenko signed the bill.
The Ukraine's Education Act has been opposed by Hungary, Romania, Bulgaria, Russia, and Moldova.
The bill came into force on Sept. 28.
On Oct. 10, head of Hungarian Foreign Ministry Peter Szijjarto refused to meet his Ukrainian counterpart Pavlo Klimkin during the former's visit to the Zakarpattia region of Ukraine.
