TEHRAN (Tasnim) Likening the US vacillating stances in the nuclear talks with Iran to the snakes and ladders game, the spokesperson for the Iranian Foreign Ministry made it clear that Tehrans enrichment program would not come to a halt by any means.

Speaking to reporters at a weekly press conference on Monday, Esmaeil Baqaei hit back at US special envoy Steve Witkoff for claiming that any deal between the US and Iran must include an agreement not to enrich uranium.

The issue of enrichment as part of the natural cycle of Irans nuclear industry is by no means negotiable, he underscored.

Enrichment is not a fantasy. Enrichment is a technology and requirement for making sure that Irans nuclear industry will go on uninterruptedly, Baqaei stated, stressing that Iran will never forgo its legitimate right to enrichment.

Likening the change in the US policies to a game of snakes and ladders, the spokesman said whenever Iran conceives that good understanding has been shaped in the talks, the US negotiators changetheir stances after returning home.

Such a flip-flop raises doubts about the US seriousness in the talks with Iran, he added.

Deploring the fresh sanctions imposed by the US against Iran, the spokesman said a difficult part of talks with the Americans is that they do not remain committed to anything.

Every new package of sanctions against Iran amounts to crimes against humanity and proves that the US feels hostility toward Iranians. One should not trust their (US) claim of being serious in diplomacy.

Reiterating Irans seriousness in the talks, Baqaei said the countrys nuclear program is totally peaceful and Tehran has nothing to hide, which is why it has opted for a diplomatic approach.

While the continuation of the (US) sanctions isnot going to have any influence on Irans determination, it only raises questions aboutthe US seriousness, he concluded.

Iran and the US have held four rounds of talks since April 12, mediated by Oman, with the purpose of reaching a deal on Irans nuclear program and the removal of sanctions on Tehran.
