Russian Ambassador Aleksandr Chepurin has announced the possibility of his country getting "even more deeply involved" in resolving the Kosovo problem, Serbian media quoted Belgrade based daily Politika.

I suggest the State Department, instead of announcement about Crimea, to explain how they ripped Kosovo from the state of Serbia without referendum, with bombs and missiles, wrote Russian Senator Aleksey Pushkov on his twitter, reports Serbian media.

He reminded that Crimea was Russian at a time when America did not exist. He commented the Washington's condemnation of the visit of Russian President Vladimir Putin to Crimea.

The President of the Czech Republic, Milos Zeman has spoken decisively against Catalonia's independence, as it would "open Pandora's box and start a chain reaction," Serbian media reported.

Czech President, Milos Zeman assessed Russian annexation of Crimea as completed act and proposed that Russia pays compensation to Ukraine for the lost territory, either financially or with raw material, BETA news agency reported.

French presidential candidate Francois Fillon mentioned the issue of Kosovo when he spoke about Crimea joining Russia.

“We have changed borders ourselves. Kosovo, for example. We think that because we are westerners everything is allowed to us - we can enter Iraq, we can bring order to any corner of the world... There is a fundamental principle of the right of people to decide for themselves. There are borders that have been established in a way, unacceptable for people,” Fillon said.

Ukraine's Ambassador in Belgrade Oleksandr Aleksandrovych says Serbia's vote against a UN resolution on Crimea "could return like a boomerang."

"There's an English expression - 'to shoot yourself in the foot'. I believe that is exactly what Serbia has done with such a vote, because at some point in the future, such a decision may come back like a boomerang in your efforts to keep Kosovo. I don't understand why you are doing this," Aleksandrovych has told the Belgrade-based newspaper Blic.
