DOHA — Qatar has dispatched diplomatic envoys to Tehran, resuming mediation efforts after weeks of stalled indirect talks between Iran and the U.S. Officials confirmed the delegation's departure Friday, aiming to restart substantive negotiations.

The move comes as tensions in the Persian Gulf remain elevated, with both U.S. and Iranian naval forces maintaining operations in the region. President Trump has called for de-escalation while maintaining pressure on Iran's regional activities and ballistic missile program. Recent incidents involving commercial shipping have highlighted the security risks.

Previous rounds of Qatari-led negotiations have foundered over core demands: Iran insists on full lifting of U.S. economic sanctions imposed since 2018, while the Trump administration says sanctions relief depends on Iran ceasing support for regional proxy groups and curbing its missile program. These disagreements have blocked progress.

Qatar, a U.S. ally and Iran's neighbor, has positioned itself as a neutral broker to stabilize regional security and protect energy supply routes through the Strait of Hormuz. The Gulf nation has invested significant diplomatic capital in these efforts over the past year.

The Qatari delegation is expected to hold initial discussions with Iranian foreign ministry officials through the weekend. A spokesperson for Iran's Foreign Ministry said Tehran is prepared to engage in constructive dialogue if U.S. proposals address Iran's core security concerns. Qatari officials aim for tangible progress within two weeks, though no immediate timeline for direct U.S.-Iranian engagement has been announced.
