EU leaders push Vučić on reforms but stay silent on Serbia’s protests

Serbian President Aleksandar Vučić dined with European Commission President Ursula von der Leyen and European Council President António Costa in Brussels last night. And what sounds like a simple diplomatic dinner was in reality a chance for the EU to ask Belgrade to deliver on EU reforms if it wants to join the block, but nothing on the protests was discussed. 

So how long can the EU keep ignoring the growing protests in Serbia before it risks losing credibility in the region?
