Today, on March 31 the framework agreement between the six world powers is expected to be signed. As BBC informs, Foreign Ministers from six world powers and their Iranian counterpart have been negotiating in Switzerland ahead of a self-imposed deadline.
While estimating the pace of the negotiations, US Secretary of State John Kerry said that it has produced "some light" but "tricky issues" remained. In his turn, China's Foreign Minister Wang Yi said that he is optimistic about the Iranian nuclear deal, claiming that the disagreements between the parties have narrowed down.
