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.

"Today Catalonia, tomorrow northern Italy, the day after Scotland, after that the Basque Country, because ETA would also want it. The following week Moravia; in Slovakia, the south... Cyprus has already been hit, and this would only immortalize the problem. No. Once you start that chain reaction, you will never stop," Zeman said during his regular weekly interview for private Czech broadcaster TV Barrandov.

Zeman warned last month, on the occasion of the referendum in Catalonia, that the international community was using double standards when it accepts a violation of Serbia's territorial integrity in the case of the secession of Kosovo, while referring to the same thing in Crimea as an illegal annexation by Russia.

"I criticized the secession of Kosovo at the time. I consider it to be a flagrant violation of the UN Security Council Resolution (1244) which, if you still remember, guaranteed the territorial integrity of Serbia with Kosovo. Unfortunately, something called double standards happened. When it's a referendum in Crimea, it's an illegal annexation, when Kosovo becomes independent then everything is fine," Zeman said during the interview.

The Czech president added that what he can do, is not to send the Czech ambassador to Pristina.

"I, as the president, reacted by not appointing our ambassador in Pristina. Because I am not appointing one, there will simply not be one there. And I do not receive the Kosovo charge d'affairs when I receive foreign ambassadors," Zeman said.
