"The US needs to return to its commitments, and if that happens, it will be possible to negotiate within the framework of the Joint Commission of the JCPOA."
He added: "If the Biden administration intends to correct the United States' wrong path, it should take practical measures."
Iran said the US rejoining the deal would be meaningless unless sanctions are lifted.
"A signature on a piece of paper will not suffice," Khatibzadeh said.
The pact is a 159-page agreement reached by Iran, China, France, Germany, Russia, the United Kingdom, and the United States on July 14, 2015.
The nuclear deal was endorsed by UN Security Council Resolution 2231, adopted on July 20, 2015.
Iran's message comes after the country's president told Biden that the "ball is in your court" over the nuclear deal.
In a televised cabinet meeting, Rouhani welcomed the end of "tyrant" Trump’s era.

US and Iran - a troubled history
- Before the 1979 Iranian revolution, Iran was one of America's biggest allies in the Middle East and was led by the US-backed Mohammad Reza Shah Pahlavi.
- However, since the seismic revolt, Iran has been led by murderous Islamic fundamentalists and tensions with Washington have remained ever since.
- On November 4, 1979, the Iranian regime took 52 US diplomats hostage in response to President Carter’s administration allowing Iran’s deposed former leader into America.
- The hostage crisis lasted for 444 days and also included a failed rescue mission which cost the lives of eight US soldiers.
- In April 1980, the US ended diplomatic relations with Iran – a break which lasted for more than 30 years.
- In April 1983, Washington blamed the Iranian-funded terror group Hezbollah for carrying out a bombing attack on the American embassy in Beirut, Lebanon.
- The assault, carried out amid a brutal civil war in Lebanon, killed 17 Americans.
- In November of that year, two truck bombs in Beirut killed 241 US peace keepers. The US again blamed Hezbollah for the incident.
- The Clinton White House, in 1995, placed a total embargo on Iran meaning US companies could not trade with the country.
- And in 2002, George W Bush included the Islamic Republic in his famous “Axis of evil” speech along with North Korea and Iraq.
- On January 3, 2020, Iran's General Soleimani was killed by a US drone strike in Iraq
