Iranian President Hassan Rouhani said here on Tuesday that the United States has failed to fulfil its nuclear obligations "accurately"."If they were committed to their promises accurately, and did not hinder the process of nuclear deal implementation, we could count on them and sit to discuss other issues with them," Xinhua news agency quoted Rouhani as saying in a live televised speech.Rouhani's remarks were a reaffirmation of the country's top leader's Monday comments on the implementation of the nuclear deal clinched between Iran and world powers in 2015."The United States has violated its obligations (over the implementation of the nuclear deal) and is busy destroying Iran's economic ties with other countries," Iran's Supreme Leader Ayatollah Ali Khamenei said on Monday.In some areas, Iran still has problems in the transfer of money via the large international banks for the transactions that it has with its economic partners, Rouhani said.The Iranian President expressed the hope that such problems will be gradually solved in the future.
