PACE (Parliamentarian Assembly of the Council of Europe) rapporteur on South Caucasus Leo Platvoet says participation of all conflicting parties is necessary in the peaceful resolution of the Nagorno Karabakh problem. Commenting on presidential elections of NKR, Platvoet said Nagorno Karabakh is not recognized by any country in the world, including even Armenia. Thus, according to the rapporteur, "the President of Karabakh will be an unrecognized figure on the international level". From the other hand, all conflicting parties must be involved in the peaceful solution of the Nagorno Karabakh conflict, Platvoet underlined. He said, the elected President of Nagorno Karabakh can play a role in the peaceful solution of the conflict as the leader of the Armenian community of Nagorno Karabakh, "Trend" reports.
