Kurz's meeting with Juncker came on the heels of a "good meeting" with European Council President Donald Tusk, during which the young leader, as he tweeted, " reaffirmed the Austrian government's pro-European position & its full commitment to further developing the EU."

"Looking forward to closely cooperating on the upcoming Austrian EU Presidency in 2018," he added.

Tusk also hailed their meeting, tweeting, "very positive and constructive discussion with Chancellor @sebastiankurz. I see in him an energetic, determined and pro-European leader."

Kurz is set to meet European Parliament President Antonio Tajani on Wednesday.
