Baghaei reiterated Iran’s firm commitment to exercising its legal and undeniable right to peaceful nuclear energy under the Non-Proliferation Treaty (NPT), affirming Iran’s full readiness to continue diplomatic engagement to demonstrate the civilian nature of its nuclear program.
He also emphasized Iran’s goal of lifting what he called “illegal and inhumane sanctions” that have long impacted the Iranian people.
Earlier, Baghaei confirmed that indirect talks remain ongoing through message exchanges, mediated by Oman’s foreign minister.
