Negotiations aimed at restoring the 2015 nuclear deal resumed in Vienna, although this round of talks appeared not to include high-level delegations from all the countries that were part of the original deal. According to Iranian state media, Iran still demands that the Islamic Revolutionary Guard Corps (IRGC) be removed from the U.S. list of terrorist organizations as a precondition to a deal. Further, Iran wants the International Atomic Energy Agency (IAEA) to abandon its investigation into traces of uranium found at previously undeclared sites.

The Iranian-flagged oil tanker Lana (formerly Pegas) will retrieve part of its cargo and return home following a ruling of the Greek Supreme Court in Iran's favor. The United States had confiscated the cargo after the tanker was impounded by the Greek authorities more than two months prior. In response, Iranian forces had seized two Greek tankers in the Persian Gulf, which have not yet been released.

Mohammad Eslami, the head of Iran's Atomic Energy Organization, said that Iran would not reactivate 27 International Atomic Energy Agency (IAEA) monitoring cameras at its nuclear sites until the United States returns to compliance with the 2015 nuclear deal. Iran had removed the cameras in June in response to a resolution criticizing it at the June IAEA Board of Governors meeting. Eslami also said that Iran would not cooperate with an IAEA probe investigating traces of uranium found at three undeclared sites, stating that the 2015 deal had already addressed all issues related to "possible military dimensions" of Iran's nuclear program.

According to U.S. National Security Adviser Jake Sullivan, a Russian delegation visited an airfield in Kashan, Iran in June and again in July to examine a showcase of Iranian drones. The delegation was shown Shahed-129 and Shahed-191 models, both of which are capable of carrying precision-guided missiles.
