TEHRAN (FNA)- A senior Syrian legislator said the US will soon shift its energy policy and start replacing Saudi Arabia with Iran for supplying crude oil as Riyadh's anti-democratic and reactionary actions are growing increasingly costly for Washington.

"The US administration assumes the (nuclear) agreement with Iran will serve its interests in the region and therefore, it is after sustainable stability and security in certain parts of the region and seeks intensified tensions in the other parts," Fayez Al-Sayegh told FNA on Monday.

He further noted the cause of the US collaboration with Riyadh' military aggression against Yemen, and said, "The White House sought to make Saudi Arabia busy with its own internal affairs and its neighbors' issues and therefore, it enmeshed Riyadh in Yemen's quagmire to somehow prevent it from meddling and troubling the nuclear agreement with Iran and confronting the Group 5+1 (the US, Russia, China, Britain and France plus Germany)."

"As events show, the US will replace Saudi Arabia with Iran to meet its oil interests since it is ashamed of being allied with a backward country in which democracy and freedom doesn�t have any meaning and women aren�t even allowed to drive a car," Sayegh underlined.

After nine days of hard work in Lausanne, Switzerland, Iran and the G5+1 reached an understanding on April 2 which laid the ground for them to start drafting the final nuclear deal over Tehran's nuclear energy program ahead of a July 1 deadline.

Reading out a joint statement at a press conference with EU foreign policy chief Federica Mogherini in Lausanne on April 2, Iranian Foreign Minister Mohammad Javad Zarif said according to the agreement, all the US, EU and UN Security Council sanctions against Iran would be lifted under the final deal.

The delegations of the seven nations are now drafting the final deal.

In relevant remarks last Wednesday, Iranian Parliament Speaker Ali Larijani lashed out at Riyadh for its attempts to spoil nuclear talks between Tehran and the G5+1.

"Isn't it ugly for a Muslim state to send its (then) foreign minister to the airport in the middle of the nuclear negotiations and ask for the failure of the negotiations and give different promises like reduction of oil price and other things," Larijani said, addressing an open session of the parliament in Tehran.

Former Saudi Foreign Minister Prince Saud al-Faisal, concerned about any US-Iran rapprochement, jetted into the Austrian capital in November, with US Secretary of State John Kerry updating the prince on his plane at Vienna airport about the talks.

Larijani said while many in Iran haven�t still accepted the Geneva agreement (November 2013) and the Lausanne statement, it is surprising that the Saudis are strenuously making attempts to damage the talks.

Larijani underlined that even if the negotiations fail, Saudi Arabia will gain nothing and Iran will continue development of its nuclear technology speedily to make the US and its allies regret their deeds in the next few years.
