"If the US had not left the negotiating table with miscalculation and had not pinned hope on [last year's] riots, this humanitarian action could have been done much earlier," Ehsan Salehi, the secretary of the government Information Council, quoted Raeisi as saying.
Raeisi made the remarks in New York while speaking to senior American media managers on Monday ahead of the 78th session of the United Nations General Assembly after Iran and the US implemented a Doha-mediated prisoner swap deal.
According to the official, the president said that Iran has no trust in the US for its violation of treaties but every single step that Washington takes to fulfill its commitments can help build confidence.
After two years of high-stakes negotiations, Iran and the US agreed to free prisoners as part of a deal that also included the release of billions of Iranian assets illegally frozen in South Korea.
The funds, owed to Iran for exports of oil and gas, had been frozen in South Korean bank accounts since 2018 after the administration of then-President Donald Trump pulled the US from a landmark nuclear deal with Iran, further aggravating tensions with Tehran.
On Monday, Iran and the US freed 10 prisoners -- five Iranians and five Americans -- after the US government unblocked the transfer of $6 billion in frozen Iranian oil funds held in South Korea.
