Hungarian Foreign Minister Peter Szijjártó on Sunday denied accusations that the special rules his government has put in place for guest workers from Russia and Belarus pose a risk to the European Union.

Workers from these two countries “will continue to undergo thorough checks when entering and staying in Hungary,” the head of Hungarian diplomacy assured via Facebook.

Hungarian regulations on guest workers until recently applied exclusively to nationals of Ukraine and Serbia. But they were extended to include Russian and Belarusian nationals in July, a development that sparked concerns about espionage, voiced in particular by Home Affairs Commissioner Ylva Jansson.

The Swede emphasized that Budapest must guarantee that Russians with a past in Moscow’s espionage services will not enter Hungarian territory and will not be allowed to travel to other EU states.

Mr. Szijjarto claimed yesterday that his country is the target of a “campaign of lies” by other European Union member states, especially by Northern European and Baltic states.

Right-wing populist Prime Minister Viktor Orban maintains good relations with the Kremlin despite the outbreak of war in Ukraine more than two and a half years ago. He traveled to Moscow and met with Russian President Vladimir Putin as part of what he described as a “peace” initiative in July, days after his country took over the rotating EU presidency, causing confusion and anger in Brussels.
