Serbian President and Serbian Progressive Party (SNS) leader Aleksandar Vucic said on Thursday he had not decided yet whether to go to Zagreb to a European People's Party Congress, saying there was hysteria in a part of the Croatian public about it.

Speaking for Serbia’s TV Pink in Geneva, where he was attending a meeting on the Western Balkans, Vucic said he still could not confirm his participation in the congress because his associates were “strategically planning it” and that he would consult them on a decision next week.

Vucic said “this hysteria in a part of (the Croatian) public” about his possible participation in the EPP congress appeared among those “who have never been in favour of regional cooperation and good Serbia-Croatia relations.”

“I can’t talk about (Croatian PM) Plenkovic, (Croatian President) Grabar-Kitarovic and other normal people in Croatia, but some have a constant need and desire for Serbia to be humiliated and as weak as possible.”

The SNS is an associated EPP member without voting rights.
