Why did Saudi foreign minister travel to Vienna uninvited?

In reaction to a surprise trip by Saudi Foreign Minister Saud al-Faisal to Vienna [the venue of ongoing nuclear talks between Iran and P5+1] and his talks with US Secretary of State John Kerry, Alef, a news website, said, “the presence of the uninvited guest on the sidelines of the Vienna talks” translated into a thank-you message from Washington to Riyadh for the latter’s efforts to send crude prices tumbling and thus put pressure on Iran and Russia.

Donyay-e Eghtesad newspaper described Saudi Arabia as a disruptor of the nuclear talks in Vienna which tries “to prevent the sides from arriving at an agreement”. It says that Saud al-Faisal is in the Austrian capital to represent Israel.

Presence of Saudi official belittled the kingdom: MP

Tasnim News Agency quoted Esmail Kosari, a member of the National Security and Foreign Policy Committee of the Iranian parliament, as saying, “The presence of the Saudi top diplomat in the venue of the nuclear talks amounts to disrespect for the kingdom.”

He went on to say, “Saudi Arabia should know that its petrodollars will not always pay off. It needs to wait and see the future of the talks more tactfully.”

Americans are selling the nuclear deadlock to Saudis

Fars News Agency filed a report on the reason why the Saudi foreign minister flew to Vienna to meet with his US counterpart. It said, “The West is trying to pitch the snag over the nuclear talks to the Saudis. Saudi Arabia and other sheikhdoms in the Persian Gulf are the ones who have to pay a price for the excessive demands of the Americans.”
