TEHRAN - Iran's Foreign Ministry said Tuesday it is fully aware of the negative consequences of a possible reinstatement of UN sanctions under the snapback mechanism and is working to prevent it.

Spokesman Esmaeil Baghaei rejected claims that Tehran is downplaying the issue, saying they are concerned about its consequences.

He said Iran has taken "considerable efforts" to avert the move, citing ongoing talks with the European parties to the 2015 nuclear deal, namely France, Britain and Germany (E3), in Geneva and consultations with other UN Security Council members.

The discussions focus on lifting sanctions and the future of Resolution 2231, which endorses the nuclear accord, Baghaei noted, adding that Tehran will continue to demonstrate transparency about the peaceful nature of its nuclear program.

He also stressed that E3 lack the legal and moral authority to trigger the mechanism.

The E3 have recently warned of using the snapback clause, which would restore all UN sanctions on Iran if it violates the nuclear agreement.
