(DUBAI) Iran would be open to talks with the United States if Washington apologises for exiting a 2015 nuclear deal and compensates Tehran, Iranian President Hassan Rouhani said on Wednesday, cautioning that U.S. calls for discussions were insincere.

The confrontation between arch foes Tehran and Washington has worsened since 2018, when U.S. President Donald Trump withdrew from Iran's 2015 nuclear deal with major powers and reimposed sanctions that have crippled Iran's economy.

Iran has refused to hold any talks with the United States, which is trying to force Tehran to negotiate a new deal, unless Washington lifts sanctions on Tehran and returns to the original agreement.

In a tweet in early June, Trump repeated Washington's call for a new deal with Tehran aimed at putting stricter limits on Tehran's nuclear work, curbs its ballistic missile program and ends its decades of regional proxy wars.

"We have no problem with talks with the U.S., but only if Washington fulfils its obligations under the nuclear deal, apologies and compensates Tehran for its withdrawal from the 2015 deal," Rouhani said in a televised speech.
