TEHRAN — Iranian officials said they expected positive economic changes with the lifting of some sanctions against the country as part of a deal struck with world powers, which begins on Monday.

The interim deal, signed in November in Geneva and completed last week, will temporarily freeze much of Tehran’s nuclear program in exchange for limited relief from the Western economic sanctions. The deal will last for six months, giving Iran and six countries involved — Britain, China, France, Germany, Russia and the United States — time to negotiate a permanent deal.

Nuclear inspectors from the International Atomic Energy Agency, the United Nations’ watchdog group, who will monitor the Iranian elements of the agreement, arrived in Tehran over the weekend, local news media reported.

Iranian leaders, including some hard-liners, have welcomed the deal, which allows the nation to freely export petrochemical products, have sanctions lifted on gold and precious metals, and create a special banking channel to facilitate payments for goods like food and medicine. These products were not affected by sanctions in the past but could not be paid for because of restrictions on all international financial transactions with Iran.
