Iran and the USA will talk to restart a 2015 nuclear deal. There will be no face-to-face meetings between high-level officials. On the table for discussion is the revival of the 2015 pact. That deal reduced economic sanctions on Iran. The pact was meant to make it harder for Iran to develop nuclear weapons. Donald Trump abandoned it. Iranian officials have always denied they have had any plans to develop nuclear weapons.
Negotiators say the talks will be difficult. There may not be any early breakthroughs. A US negotiator said: "The primary issues to be discussed are...on the one hand, the nuclear steps that Iran would need to take to return to compliance with the 2015 nuclear accord, and on the other hand, the sanctions-relief steps that the US needs to take." Iran will "reverse its remedial measures...taken because of the opposite side's violation of the treaty".
