"Iran has not made a decision to build a nuclear weapons facility. It is administration policy to not allow Iran to obtain nuclear weapons. We're monitoring enrichment activity very, very closely. But administration policy remains same: we will not allow Iran to develop nuclear," Narang said, according to Sputnik.
The State Department said earlier in the week that the United States is not taking part in direct talks with Iran on the return to the nuclear agreement, formally known as the Joint Comprehensive Plan of Action (JCPOA).
In 2015, Iran signed the JCPOA with China, France, Germany, Russia, the United Kingdom, the United States and the European Union.
The agreement committed Iran to scaling back its nuclear program in exchange for sanctions relief. The United States unilaterally withdrew from the agreement in 2018 but then resumed talks with Iran in a bid to revive the deal. The talks have since hit a deadlock.
Iran has repeatedly said its nuclear program is solely intended for peaceful purposes.
