The United States says it would start imposing sanctions over Iranian exports of enriched uranium allowed under a nuclear deal rejected by President Donald Trump, although it granted waivers to allow the accord to survive. Under the 2015 deal, which still enjoys strong support among European powers, Iran was limited to keeping 300 kilograms of uranium enriched up to 3.67 percent — far below the level needed to build nuclear weapons. As part of the agreement, Iran was to sell any enriched uranium above that threshold on international markets in return for natural uranium.
But in a policy change, Secretary of State Mike Pompeo has said the United States would start to impose sanctions on anyone involved in the trade of natural for enriched uranium.
At the same time, the United States issued new three-month waivers to allow the continuation of the major parts of the nuclear deal.
