The Iranian delegation at the Vienna talks wants all sanctions “to be lifted at once” and a proposal on verifying the removal will be submitted later.
Iran has provided European powers with drafts on sanctions removal and nuclear commitments as world powers and Tehran try to reinstate the nuclear deal.
"We have delivered two proposed drafts to them...Of course they need to check the texts that we have provided to them. If they are ready to continue the talks, we are in Vienna to continue the talks," Political Deputy at the Ministry of Foreign Affairs of Iran Ali Bagheri Kani said on Thursday.
The announcement came after three days of indirect talks between Iran and the United States on bringing both fully back into the deal.
A European diplomat in Vienna confirmed draft documents had been handed over.
Under the pact, Tehran limited its uranium enrichment programme, a potential pathway to nuclear weapons though Iran says it seeks only civilian atomic energy, in exchange for relief from US, European Union and UN economic sanctions.
Israel opposes renewal
In 2018, then-US President Donald Trump abandoned the deal, calling it too soft on Iran and reimposed harsh US sanctions, spurring Tehran to breach nuclear limits in the pact.
Estimating that 70-80 percent of a draft agreement was completed when Iran and world powers last met in June, a senior European diplomat said on Tuesday that it remained unclear if Tehran would resume talks where they left off.
While Bagheri Kani had said everything negotiated during six rounds of talks between April and June was open for discussion, a member of Iran's delegation said "elements in the previous unapproved draft that were in conflict with the nuclear deal were revised and gaps were filled".
Israel, which opposed the original 2015 pact as too limited in scope and duration, urged world powers on Thursday to halt the talks immediately.
It cited a UN nuclear watchdog report that Tehran has begun enriching uranium with more advanced centrifuges in its Fordow plant dug into a mountain where any enrichment had been banned under the deal.
The International Atomic Energy Agency said on Wednesday Iran had started the process of refining uranium to up to 20 percent purity.
