The United States and Iran described the first three rounds of negotiations over Iran’s nuclear program as constructive, but comments from Washington and Tehran suggest that key differences remain ahead of the fourth round of talks. 

Since President Donald Trump announced on April 7 that the United States and Iran agreed to begin talks, Iranian Foreign Minister Abbas Araghchi and U.S. Special Envoy to the Middle East Steve Witkoff met three times. The third round of negotiations in Oman on April 26 included technical-level talks between the two sides. 

The fourth round of talks between Iranian Foreign Minister Abbas Araghchi and U.S. Special Envoy Steve Witkoff is about to kick off, with previous meetings injecting much-needed momentum into President Donald Trump’s push for a diplomatic resolution to the Iranian nuclear crisis.
