Serbian President Aleksandar Vucic probably won’t seek a second term, as he intends to complete the work needed to lead his country into the European Union when his mandate ends in 2022.

Vucic, who as the leader of the ruling Serbian Progressive Party is the Balkan state’s most powerful politician, said in an interview that he’d announce proposals to tackle the issue of Kosovo -- the biggest hurdle to EU entry -- by early April. He also repeated a vow that Serbia will not join EU nations in imposing sanctions against Russia, though he "can’t guarantee what will happen after I leave this post."
