TEHRAN — Iran’s new president on Sunday called on the West to abandon the “language of sanctions” in dealing with the Islamic Republic over its rogue nuclear program.

President Hasan Rouhani spoke after being sworn in as president in an open session of parliament, capping a weekend that saw him endorsed by Ayatollah Ali Khamenei, Iran’s supreme leader.

Rouhani, who won a landslide victory in the June 14 presidential elections, continued his call for dialogue with the West while asking foreign powers to respect Iran in its negotiations.

“If you seek a suitable answer, speak to Iran through the language of respect, not through the language of sanctions,” the president said in a speech broadcast live by Iranian state television. He later added that any negotiations would require “bilateral trust building, mutual respect and the lessening of hostilities.”

Iran is under United Nations sanctions as well as unilateral Western oil and banking sanctions over its refusal to halt uranium enrichmen.

Rouhani replaces Mahmoud Ahmadinejad, who struck a hard-line approach when dealing with the West and its sanctions over the nuclear program. The sanctions have hit the country’s vital oil exports and blocked transactions on international banking networks. Inflation is running at more than 35 percent. The Iranian rial has lost more than two-thirds of its value against the US dollar since late 2011.

Many Iranians and foreign diplomats hope that Rouhani, a former top nuclear negotiator, can strike a more conciliatory tone in negotiations. Those hopes could be seen by the attendance at his swearing in, as the audience included leaders and other representatives from more than 50 countries. It was the first time since Iran’s 1979 Islamic Revolution that foreign dignitaries attended the swearing-in ceremony of an Iranian president.

Iran did not invite Israeli or American representatives to the inauguration.

In Washington, White House spokesman Jay Carney said Rouhani’s inauguration “presents an opportunity for Iran to act quickly to resolve the international community’s deep concerns over Iran’s nuclear program.”

“Should this new government choose to engage substantively and seriously to meet its international obligations and find a peaceful solution to this issue, it will find a willing partner in the United States,” Carney said in a statement.

During his speech, Rouhani said Iran opposes “any change in political systems through foreign intervention.” Iran is a close ally of Syrian President Bashar Assad, whose country remains in the grips of a bloody two-year civil war. Assad’s government has received fighters from the Iranian-backed Hezbollah, helping government forces gain ground in recent weeks.

“Peace and stability in all neighboring regions is a need and necessity for Iran,” Rouhani said.

Ahmadinejad’s eight-year presidency was marked by confrontation with the West over Iran’s nuclear program, economic suffering due to an increase in global sanctions, and persistent denial of the Holocaust.

Rouhani was believed to have garnered the votes of Iran’s more reform-minded voters, even though he is a veteran of the ruling clerical establishment and his candidacy was authorized by Khamenei.

On Friday, Rouhani attracted world attention when he called Israel an “old wound” at an event for International Quds Day in Iran, attending by millions. Earlier in the day, he was misquoted, with media outlets reporting that he had called for the “wound… to be removed,” a statement promptly and sharply criticized by Prime Minister Benjamin Netanyahu.

“There is an old wound on the body of the Islamic world, under the shadow of the occupation of the holy lands of Palestine and Jerusalem,” read the corrected ISNA quote by Rouhani. Netanyahu subsequently retracted his response.

In his remarks Friday, Rouhani also expressed doubts about the possibility of an Israeli-Palestinian peace deal as the two sides resumed negotiations in Washington last week.

“Israelis show a compromising face to the world but continue their expansionism in practice,” Rouhani said, according to Fars, another semi-official news agency. “This rally is a reminder that Muslim people will not forget their historical right and they will resist oppression and invasion.”

Syria’s state-run news agency SANA reported Sunday that Rouhani told Syria’s prime minister that no force in the world would shake the alliance between the two countries.

Meanwhile, Rouhani also presented a list of ministers he wants for his Cabinet to parliament. The core of his team has figures whose academic pedigrees include institutions in California, Washington and London.

Rouhani proposed Mohammad Javad Zarif, a diplomat at Iran’s UN Mission in New York for five years, to serve as foreign minister. He also proposed Mahmoud Alavi, a cleric and former lawmaker, as minister of intelligence and Hossein Dehghan, a former commander in the powerful Revolutionary Guards, as defense minister. Others include officials who served in the administrations of both reformist President Mohammad Khatami and centrist President Akbar Hashemi Rafsanjani.

Khamenei, however, has final say in all key matters, including Rouhani’s key Cabinet posts. On Saturday, Rouhani received a kiss on the forehead from Khamenei, a blessing from the supreme leader.
