Vice President Biden visited Pristina. Majlinda Kelmendi, Kosovo's first Olympic gold medalist, was among the high level diplomats who met him at the airport. I'm told he spent more time speaking with her than the other diplomats.
Biden was here in the ongoing negotiations to get Kosovo and Serbia to normalize relations. Serbia believes Kosovo belongs to Serbia. Kosovo believes they're free from their former oppressors. As a condition to join the EU, they must normalize diplomatic relations. From what little I know, that'll take some time. It won't happen in this or the next presidential administration.
