Iran's parliament approved a government economic reshuffle on Saturday, days before new U.S. sanctions on Tehran's oil exports take effect, after President Hassan Rouhani said Washington was isolated among its allies in its confrontation with Iran.

"It does not happen often that the U.S. makes a decision and its traditional allies abandon it," Rouhani told parliament before the vote to approve the new appointments.

Academic Farhad Dejpasand, widely seen as a technocrat, received a vote of confidence by a wide margin as the new minister of economics and finance.
