In 2015, Iran signed an agreement with the P5+1 group – the five permanent members of the United Nations Security Council (the United States, Russia, China, the United Kingdom and France) plus Germany – to regulate and monitor Tehran’s nuclear activities in exchange for lifting sanctions.
However, in 2018, under former President Donald Trump, Washington unilaterally withdrew from the agreement and began reimposing “unprecedented sanctions” on Iran. In response, Tehran gradually suspended its commitments under the deal and took several steps, including resuming high-level uranium enrichment.
