Iran's new Foreign Minister Abbas Araghchi plans to improve relations with the West amid international sanctions and political isolation, DPA reported, quoted by BTA.
The ministry will try to "overcome tensions with Washington and restore relations with European countries", the 61-year-old diplomat was quoted by ISNA news agency as saying after being confirmed in the post.
However, he called on the West to abandon its "hostile position" regarding the revival of the 2015 Vienna nuclear deal.
Araghchi built part of his diplomatic career as ambassador to Finland and Japan. He then served as deputy foreign minister under former President Hassan Rouhani and played a key role in the nuclear negotiations.
He is considered a champion of better relations with the West and of direct, albeit critical, dialogue with the United States.
Critics have little expectation of the diplomat, who is likely to continue Iran's support for radical groups in their fight with their long-time adversary Israel.
Negotiations to revive the nuclear deal have been stalled for more than two years.
Almost a decade ago, Tehran agreed to curb its nuclear program in exchange for the lifting of UN sanctions that had severely affected Iran's oil exports and banking sector.
The main objective of the agreement was to prevent Tehran from developing nuclear weapons.
But after the US withdrew from the agreement under Donald Trump In 2018, Iran began to gradually default on its obligations under the treaty.
