Iran has accepted inspections in its military sites while world powers would progressively lift international economic sanctions imposed on the country.

Negotiations between Iran and six world powers; United States of America, United Kingdom, France, China, Russia and Germany that  began in 2006  on Iran’s nuclear programme, reached a historic happy end on Tuesday, July 14, 2015 with an agreement struck in Vienna, Austria. The world powers called P5+1 set out to compel Iran scale back its sensitive nuclear activities  to ensure that it cannot build a nuclear weapon  and Iran on its part, wanted the crippling international sanctions lifted, insisting that its nuclear work was peaceful, BBC said.

The agreement gives UN nuclear inspectors extensive but not automatic access to sites within Iran. RFI reported that following the terms of the agreement, world powers would progressively lift sanctions imposed on Iran beginning in 2016 and maintain the embargo on arms for the period of five years. The ban on the sale of missiles to Iran will be maintained for at least eight years but the supply would be possible with the UN accord, Russian Foreign Minister Serguei Lavrov explained, RFI reported.  Iran on its part, has reportedly accepted to allow UN nuclear inspectors on its military sites and the investigation into the past nuclear programme.

Mohammad Javad Zarif, Iranian Foreign Minister said the deal was "not perfect for anybody'', but that it was the "best achievement possible that could be reached", BBC quoted. He further described the agreement as historic saying that it opened, “new chapter of hope,” BBC said. Iran's Press TV reportedly said, "Iran has been recognised as nuclear power entitled to fuel cycle and enrichment." The European Union Foreign Policy Chief Federica Mogherini described the nuclear deal as, "a sign of hope for the entire world. It is a decision that can open the way to a new chapter in international relations," BBC quoted her as saying.

The happy end of the negotiations has led to another significant step forward being the signing of a roadmap between Iran and the International Atomic Energy Agency (IAEA)  to resolve outstanding issues. The roadmap is “for the clarification of past and present outstanding issues regarding Iran's nuclear programme,” BBC quoted IAEA Chief Yukiya Amano as having told reporters in Vienna. Describing the agreement as a "significant step forward", he said, it would allow the agency to "make an assessment of issues relating to possible military dimensions to Iran's nuclear programme by the end of 2015,” BBC said.
