The United States and European Union lifted sanctions on Iran's oil, financial, and other sectors on January 16, after the International Atomic Energy Agency verified that Iran had dismantled major components of its nuclear program.  Iran also received access to roughly $100 billion in frozen assets, while hundreds of Iranian entities were removed from the U.S., E.U., and U.N. blacklists. Iran's commitments under the nuclear deal included: shipping 98 percent of its low-enriched uranium to Russia; dismantling more than 12,000 centrifuges; and pouring cement into the core of the Arak reactor.  In parallel to the implementation of the nuclear deal, the United States and Iran reached agreement on a prisoner exchange, which included the release of five Americans.  In return, seven Iranians were released, and 14 others were removed from the Interpol wanted list.
