President Hassan Rouhani called for close collaboration between the government and incoming parliament, considering it vital to revive the domestic economy.
"The resolution of economic problems is contingent on consultations between the government and the Majlis," Rouhani told the newly-elected lawmakers to parliament in a conference in Tehran on Saturday, IRNA reported.
"People expect to see greater coordination and cooperation between the government and parliament to help resolve problems and achieve sustainable economic growth."
Iran emerged from years of economic sanctions in January when the nuclear deal clinched six months earlier with major powers went into effect. It temporarily curbed Tehran's nuclear program in return.
"Improvement in the business climate and promotion of economic and legal security begin with the enactment of clear and transparent laws in the parliament," he said.
The president's efforts to jumpstart the economy by reopening the domestic market to investors and firms abroad has met opposition from conservatives, including those who form the majority in the outgoing parliament.
Rouhani's moderate supporters and reformist allies made stunning gains in the recent parliamentary elections against conservative candidates, robbing them of their long-term majority in the 290-member legislature.
The new parliament is scheduled to start work at the end of this month.
"The people sent a message in the polls that they still have faith in the line of thinking of 'moderation and prudence'," he said.
"With the people's choice in elections, we now have a greater responsibility than before."
Rouhani urged the three branches of government to cooperate in line with the Iranian Constitution.
Following the lifting of sanctions, Iran has pledged to ramp up its oil output and rejected a production freeze deal proposed by Saudi Arabia and other major oil producers, insisting it will not join the freeze until it recovers its pre-sanctions market share of about 4 million barrels per day.
It has also been struggling against the adverse effects of the remaining US sanctions that have kept foreign companies and economic institutions wary of entering Iran's market.
"In crude exports, we will restore our pre-sanctions status and part of the banking problems will be resolved soon. Other obstacles will also be removed gradually," Rouhani said.
