During the talks in Islamabad, the United States floated the idea that Iran introduce a 20-year moratorium on uranium enrichment, APA reports citing Axios news portal.
"The US proposed that Iran accept a 20-year moratorium on uranium enrichment during negotiations in Islamabad," the portal wrote, adding that "the Iranians countered with a short ‘single-digit’ period."
The portal’s source in the US administration said the sides continue to dialogue in order to reach an agreement.
