Iranian foreign minister Javad Zarif tweeted photos of Soleimani and thanked the Swiss government for their assistance in the swap. Iranian Foreign Minister Mohammad Javad Zarif confirmed that the USA freed Iranian scientist Massoud Soleimani.
'Many thanks to all engaged, particularly the Swiss government, ' which has looked after USA interests in Iran in the absence of diplomatic ties, Zarif added.
USA citizen Xiyue Wang will be returning to the United States after being held prisoner in Iran for 3 years on spying charges. The U.S. accused Soleimani of violating sanctions against Iran by attempting to export biological materials in the form of human growth hormone without authorization.
Soleimani, a stem cell expert, was arrested at Chicago airport in October 2018 for allegedly attempting to export biological materials to Iran in violation of us sanctions on Iran over its nuclear programme.
Xiyue Wang, 38, a Princeton University student, was exchanged for Iranian scientist Professor Massoud Soleimani early on Saturday as part of a prisoner exchange brokered by the Switzerland government.
Switzerland represents United States interests in Iran.
The U.S. had repeatedly called for his release.
Iran and the USA have had an increasingly strained relationship in recent years and share no diplomatic links.
Wang's wife, Hua Qu, expressed gratitude for "to everyone who helped make this happen".
On Saturday, Qu celebrated her husband's release, saying in a statement: "Our family is complete once again". At least two American families of detainees, while praising Wang's release, questioned why their loved ones didn't come home as well.

Is the public ready for Prince Charles to rule? "It's not her call - and it's not his call", said Sally Bedell Smith. However, despite all of these controversies, the Queen feels that she is still in control.
U.S. media say the prisoner swap was carried out in Switzerland.
Princeton President Christopher Eisgruber said in a statement posted on Twitter that the university's community "is overjoyed that Xiyue Wang can finally return home to his wife and young son, and we look forward to welcoming him back to campus".
He is now in Germany, where he will undergo a medical examination before returning to the USA, the official said.
Iran released video in November 2017 of Wang allegedly trying to smuggle documents. His family and the university have always said he was in Iran for research into a history degree and denied spying.
Wang's freedom came in exchange for Soleimani, a medical research scientist who was arrested in October 2018.
The United States and Iran don't have direct relations and conduct foreign affairs through Switzerland as an intermediary.
Iranian Supreme Leader Ali Khamenei has long subscribed to a "government of resistance" that seeks to avoid overentanglement with the West. They continued later: "Iranian authorities continue to play a cruel game with our father's life, and with our family".
