Iranian President Hassan Rouhani picked a cabinet of experienced technocrats as he took the oath of office, saying he hoped confidence-building with foreign powers would help resolve the nuclear dispute and ease international sanctions.
Since his election by a wide margin over conservative rivals in June, many inside and outside Iran have pinned their hopes of a diplomatic resolution to the dispute over Tehran's nuclear program on Rouhani, a cleric whose watch-word is moderation, but who is still very much an Islamic Republic insider.
The only way for interaction with Iran is dialogue on an equal footing, confidence-building and mutual respect as well as reducing antagonism and aggression, Rouhani said in a speech after taking the oath of office in parliament.
If you want the right response, don't speak with Iran in the language of sanctions, speak in the language of respect.
Signalling his wish to get straight down to work, Rouhani immediately presented his list of cabinet nominees to the parliament speaker even though he has two weeks to do so.
Parliament must approve the proposed ministers before they can take office. The speaker said the assembly would review the nominees in the next week.
Rouhani picked Iran's former ambassador to the United Nations, Mohammad Javad Zarif, as foreign minister. Zarif is a respected diplomat, well known to top U.S. officials including Vice President Joe Biden and Defence Secretary Chuck Hagel.
Western envoys familiar with Zarif have expressed hope that his appointment may be a sign of Rouhani's interest in breaking the deadlock between Iran and the United States.
Rouhani chose Bijan Zanganeh to return to the post of oil minister which he held from 1997 to 2005. Though he worked under the reformist government of former President Mohammad Khatami, Zanganeh is a non-partisan technocrat thought to enjoy the protection of Khamenei.
As oil minister, Zanganeh helped attract billions of dollars of foreign investment into Iran's vital oil and gas sector, but that was before the imposition of stringent sanctions on the industry.
Ali Tayyeb-Nia, Rouhani's choice to head the Ministry of Economy, has held government positions during the presidencies of reformist Khatami, centrist Akbar Hashemi Rafsanjani and conservative Mahmoud Ahmadinejad.
Tayyeb-Nia is an economist who has specialised in the study of inflation, which Rouhani said last month stood at 42% and which must be reduced to bring a measure of economic relief to Iranians.
