Iran signs an interim agreement with the P5+1 countries, limiting its nuclear program in exchange for reduced sanctions.

Iran, officially the Islamic Republic of Iran (IRI) and also known as Persia, is a country in West Asia. It borders Iraq to the west, Turkey, Azerbaijan, and Armenia to the northwest, the Caspian Sea to the north, Turkmenistan to the northeast, Afghanistan to the east, Pakistan to the southeast, and the Gulf of Oman and the Persian Gulf to the south. Iran ranks 17th globally in both geographic size and population and is the sixth-largest country in Asia. Iran is divided into five regions with 31 provinces. Tehran is the nation's capital, largest city, and financial center.

On 24 November 2013, the Joint Plan of Action, also known as the Geneva interim agreement, was a pact signed between Iran and the P5+1 countries in Geneva, Switzerland. It consists of a short-term freeze of portions of Iran's nuclear program in exchange for decreased economic sanctions on Iran, as the countries work towards a long-term agreement. It represented the first formal agreement between the United States and Iran in 34 years. Implementation of the agreement began 20 January 2014.

The P5+1 refers to the UN Security Council's five permanent members ; namely China, France, Russia, the United Kingdom, and the United States; plus Germany. The P5+1 is often referred to as the E3+3 by European countries. It is a group of six world powers which, in 2006, joined together in diplomatic efforts with Iran with regard to its nuclear program.

Iran's nuclear program, one of the most scrutinized in the world, has sparked intense international concern. While Iran asserts that its nuclear ambitions are purely for civilian purposes, including energy production, the country historically pursued the secretive AMAD nuclear weapons project. Both the International Atomic Energy Agency (IAEA) and analysts have warned that Iran's current uranium enrichment levels exceed what is necessary for peaceful purposes, reaching the highest known levels among countries without military nuclear programs. This has raised fears that Iran is moving closer to developing nuclear weapons, a prospect that has led to rising tensions, particularly with Israel, the United States, and European nations. The issue remains a critical flashpoint in the Middle East, with ongoing military and diplomatic confrontations. According to The New York Times in 2025, "If Iran is truly pursuing a nuclear weapon—which it officially denies—it is taking more time than any nuclear-armed nation in history."
