Representatives from the United Kingdom, France, and Germany gathered at Iran's consulate. The talks between the countries were the first since Iran's 12-day war with Israel in June, when American bomber planes attacked nuclear-related facilities in the country.
The talks, which ended after four hours, focused on the possibility of reintroducing the sanctions against Iran that were lifted in 2015 in exchange for Iran agreeing to restrictions on its nuclear energy program.
European leaders have said that the sanctions will be reintroduced at the end of August if no progress is made to restrict Iran's nuclear energy program.
Tehran, on its part, has said that the US – which withdrew from the 2015 agreement during President Donald Trump's first term – must rebuild trust in its role in the negotiations.
Iran has several times threatened to leave the UN's Non-Proliferation Treaty, which binds the country to refrain from developing nuclear weapons, if the sanctions are reintroduced.
Kazem Gharibabadi, Iran's envoy, described Friday's talks as "serious, open, and detailed." In a post on X, he said that both sides discussed relief from the sanctions and agreed on continued talks.
