The U.S. and Iran swapped detainees in Zurich. In a statement, Secretary of State Pompeo asserted that “Xiyue Wang, who has been held on false charges in Iran for over three years, has now been released… the U.S. will not rest until we bring every American detained in Iran and around the world back home to their loved ones”. Pompeo also noted that “we… are pleased that Tehran has been constructive in this matter”. In a tweet, President Trump said "thank you to Iran on a very fair negotiation. See, we can make a deal together!"; in remarks the same day he asserted that “I think it was great to show that we can do something. It might have been a precursor as to what can be done”. Iran’s foreign ministry in parallel indicated that “Professor Masoud Soleimani, who had been detained on the bogus charge of violating the U.S.’s illegal sanctions… has been released and is going home”. On 9 December, Foreign Minister Zarif asserted that Iran was “fully ready for comprehensive prisoner exchange. The ball is in the U.S.’s court”.
