Iran has rejected the Biden administration’s offer to relaunch negotiations over a new nuclear deal in exchange for lifting some sanctions before it was even proposed. “A senior Iranian official tells Press TV that Tehran will stop its 20% uranium enrichment only if the US lifts ALL its sanctions on Iran first,” Iranian state-run Press TV said on its website, according to The Jerusalem Post. “The official said Tehran will further reduce its commitments under the 2015 nuclear deal if the US does not lift all sanctions, warning that Washington is rapidly running out of time.” This is the third time the Islamic Republic has turned down the United States’ offer to resume talks about a new nuclear deal. Politico reported Monday that the Biden administration had planned to put forward a new proposal as soon as this week. The proposal would ask Iran to stop some of its nuclear activities — like the enrichment of uranium to 20 percent purity — if the U.S. lifted some of its economic sanctions. The proposal is “more than anything, about trying to get the conversation started,” a source familiar with the situation told Politico.
