Turning to the negotiations between Serbia and Kosovo. Talks are under a new cloud of uncertainty following the arrest of a senior Serbian official. Serbia continues to refuse to recognize Kosovo's independence, which was declared in 2008. CGTN's Aljosa Milenkovic reports on the two sides, which fought a brutal war in 1999, and still have a way to go.

This is the Serbian government building where the office for Kosovo is located. The workers inside are in charge of everything regarding the breakaway Serbian province. But these days they don't have much to do, since all the negotiations with Kosovo are on hold.

And this is why the violent arrest of Serbian chief negotiator Marko Djuric last month in an ethnically divided town in northern Kosovo. He was paraded through the streets of the capital Pristina and tensions flared. Just day after the arrest, as seen in this YouTube video, Serbian air force fighter jets flew low along the administrative lines with Kosovo. People in Serbia also reported seeing tanks of the Serbian army on the move.

CEDOMIR ANTIC HISTORIAN "Serbia is not willing, nor capable to reintegrate entire Kosovo and Metohija in its state organism. I believe that Kosovo Albanians don't want any tie with Serbia, and I think that the worst outcome could be the frozen conflict. I think that best solution could be division of Kosovo."

Dividing Kosovo is not a new idea. It's been frequently mentioned, but few support it.

VUK JEREMIC FORMER PRESIDENT OF UN GENERAL ASSEMBLY "My understanding is that there is a number of international players including permanent members of the Security Council who are opposing this. At least they are opposing at this very moment. And as for long is such opposition that is not viable solution. Because as I said the final solution has to be confirmed in the Security Council and for as long there is one permanent member or more permanent members that are opposing it, it's not gonna pass."

EU brokered negotiations between Belgrade and Pristina have so far produced just modest results, characterized as one step forward followed by two steps back. And even those are now are on hold.

ALJOSA MILENKOVIC BELGRADE It is a conflict which didn't start some 20 years ago, but spanned for over a century between the Serbs and the Albanians. And yet, even today there is no end in sight, with both sides claiming their rights over that territory and tensions still brewing over that part of the Balkans. Aljosa Milenkovic, CGTN, Belgrade.
