BUDAPEST, June 13. /TASS/. The start of negotiations with Ukraine on joining the European Union, scheduled for June 15, will be only the first step in a long and complex process that may take many years, Hungarian Prime Minister Peter Magyar said, warning that if Kiev fails to fulfill its obligations, the process will be stopped.

He confirmed that thanks to the agreement on the restoration of the rights of the Hungarian minority in Transcarpathia, Hungary withdrew its objections to the start of the negotiations.

"Ukraine has officially included the provisions of the Hungarian-Ukrainian bilateral agreement in its action plan prepared as part of the EU accession process. This means that the fulfillment of the Ukrainian obligations included in the Hungarian-Ukrainian legal agreement on the rights of the Hungarian minority in Transcarpathia will now meet the expectations of the EU," he said in a video broadcast by national TV channels.

"In other words, the fulfillment of Ukrainian obligations will be constantly monitored in the future by the European Commission and the European Council. If Ukraine fails to fulfill its obligations regarding the rights of the Hungarian minority, it will not be able to move forward in the accession process.
