Foreign Minister Nikola Selakovich noted that these “referenda” are contrary to the UN Charter and the generally recognized principles and norms of international law.

Serbia does not recognize the results of pseudo-referendums on the Ukrainian lands occupied by Russia, since this is completely contrary to the state and national interests of the country.
This was stated by the Minister of Foreign Affairs of Serbia Nikola Selakovich, writes the local edition of ” Politics “.
He noted that the “referenda” held in the occupied Ukrainian territories are contrary to the UN Charter and the generally recognized principles and norms of public international law. Therefore, Serbia cannot agree with their results.
“On the one hand, our fundamental commitment to the principles and norms of public international law, the Charter of the United Nations, and on the other hand, this would be completely contrary to our state and national interests, completely contrary to our policy of maintaining territorial integrity and sovereignty and commitment to the principle of inviolability of borders “Selakovich said.
