A senior Iranian official said on Saturday Iran does not trust West and it could abandon a nuclear deal after signing.
“We came to the negotiations here in Vienna with distrust, and that is a fact; we do not trust the Western negotiators at all. They do not trust us, either,” Iran’s Deputy Foreign Minister Abbas Araghchi told reporters at the end of the latest round of nuclear talks in Vienna.
Araghchi signaled that both sides could abandon the nuclear talks.
"Thus all the provisions in a deal... whenever each party feels the other side is violating the commitments, they can snap back and implement whatever existed before the agreement,” he said.
"We have taken every necessary measure so this would happen for us. Naturally, the other side will do the same for sanctions."
Iran reached a tentative deal on April 2 with the P5+1 countries to allow UN inspectors to carry out more inspections under an "Additional Protocol" to the Non-Proliferation Treaty in return for lifting of economic sanctions on Iran.
The sides aim to reach a final deal before a June 30 deadline.
Western countries have long claimed that Iran is building a nuclear bomb. Tehran says its nuclear programme is peaceful and has purely civilian aims.
