Iran has expressed its readiness to accept some limits on uranium enrichment in talks with the US, but is seeking guarantees that President Donald Trump will not abandon another nuclear pact. The two countries are set to hold a second round of negotiations in Rome after positive first-round talks in Oman. Trump previously abandoned the 2015 nuclear pact and reimposed sanctions on Iran. Tehran has set red lines that it will not compromise on, including dismantling centrifuges, halting enrichment, reducing enriched uranium storage, and negotiating over its missile program. Iran has stated that reaching a deal with the US is possible if realistic demands are made and if the US demonstrates seriousness of intent.
