A fourth round of negotiations between the United States and Iran concerning Tehran’s nuclear program has started in Oman, according to Iranian state media reports. The talks are part of ongoing diplomatic efforts to address longstanding disputes over Iran’s nuclear activities, which Western powers fear could lead to the development of nuclear weapons, a claim Iran denies. Previous rounds of negotiations have failed to yield a comprehensive agreement, largely due to deep divisions over the scope of Iran’s nuclear enrichment, the extent of international inspections, and the lifting of US-imposed sanctions. The current talks in Oman are viewed as a critical attempt to bridge these gaps, with both sides under pressure to prevent the collapse of the negotiation process. The outcome of these discussions could have significant implications for regional stability and international security, as well as for the future of the 2015 Joint Comprehensive Plan of Action (JCPOA), which the US exited in 2018. Oman has historically played a mediating role in US-Iran relations, providing a neutral ground for dialogue. The details of the ongoing discussions have not been made public, but diplomatic sources suggest that the focus remains on limiting Iran’s nuclear capabilities in exchange for sanctions relief. The talks are being closely watched by international observers, given their potential impact on Middle Eastern geopolitics and global non-proliferation efforts.
