O'Brien in Belgrade on Saturday for meetings with Serbia's leaders

US Assistant Secretary of State for Europe and Eurasia James O'Brien will visit Belgrade this Saturday for meetings with Serbia's leaders, President Aleksandar Vuciq and Chief Prime Minister Ana Brnabiq, the Serbian Presidency announced on Friday.

The senior US official will first meet with Brnabyqi and then with President Vuchıq on Saturday morning, broadcast Radio Free Europe.

During an interview for Pink television earlier Friday, the Serbian president named the upcoming meeting with the US official as a “difficult and important talks”.

O'Brien's visit to Serbia comes at a time when official Belgrade criticised the West after the Parliamentary Assembly of the Council of Europe supported Kosovo's membership in this organisation, despite Serbia's efforts to make it impossible and despite the Ohrid Agreement, under which Serbia pledged it would not prevent Kosovo's membership in international institutions

Kosovo authorities accused Serbia on April 17th of detaining more than 1,400 Kosovars for more than 20 hours at its border crossings with Croatia and Hungary, which were passing the transit between Serbia.

Serbia denied the accusations, saying the delays were caused by additional security measures at the border, and that the movement of Kosovo citizens “has not been restricted”.

The Kosovo government named these actions Serbia's revenge on support from the Council of Europe's Parliamentary Assembly for Kosovo's membership in the organisation.

That is why the US State Department and the European Union reacted, criticising Serbia for violating the free movement agreement between the two countries.

On Friday, Vuciqi named it the hypocritical “” the international community's response to the ban on Kosovo citizens in Serbia.

His visit also comes a day before the elections for the dismissal of Albanian mayors in the four majority Serb municipalities in northern Kosovo, which could be boycotted by Serb populations there.

The Serbian list, the largest party of Kosovo Serbs to enjoy the support of official Belgrade, has called on Serbs to boycott the April 21st vote.

Meanwhile, Serbia and Republika Srpska in Bosnia and Herzegovina are campaigning against a draft resolution, which is being discussed in the United Nations to declare July 11th as the International Genocide Memory Day in Srebrenica.

Vuciq said last week that Serbia would fight against the adoption of this resolution in the UN, which would blame Serbs. He fears the resolution could set the stage for Bosniaks to seek war damages from Serbia, the ally of Bosnian Serbs during the war.

The Republika Srpska Parliament in Bosnia and Herzegovina approved a report Thursday that stresses that the killing of 8,000 Muslims in Srebrenica during the Bosnian war does not constitute genocide.

The UN General Assembly is expected to vote in early May on this draft resolution.

In 2007, the International Court of Justice pronounced genocide crime in Srebrenica, in which more than 8,000 Bosniak men and boys were killed in 1995 by the Republika Srpska Army.

The Srebrenica massacre has been named the worst in Europe since World War II.
