February–July 2014 negotiations[edit]
Main article: Comprehensive agreement on Iranian nuclear program
During February to July 2014 the P5+1 and Iran have held high-level negotiations on a comprehensive agreement on Iran's nuclear program in Vienna, Austria. After six rounds of talks the parties missed the deadline for reaching a deal and agreed to extend the negotiations through November 24. Additionally, it was agreed that the U.S. will unblock $2.8 billion in frozen Iranian funds, in exchange for Iran continuing to convert its stocks of 20% enriched uranium into fuel.[318]
The EU Court of Justice annulled a freeze of the Iranian Sharif University's assets since the EU could not provide sufficient evidence of the university's links to the nuclear program of Iran.[319]
