Foreign Ministry spokesman Hossein Jaber Ansari said the successful implementation of the Joint Comprehensive Plan of Action, as the nuclear deal reached between Iran and world major powers last July is officially called, may open the door for talks about other issues.
In the first press conference since his appointment, Ansari said on Monday the US should show a strong desire for full implementation of the nuclear deal, IRNA reported.
"Although the two sides engaged in extensive talks in the course of nuclear negotiations, but those were limited to the nuclear issue," he said.
"We have not yet seen signals from the US."
Ansari pointed to a bill recently passed by the US House of Representatives introducing modifications to the visa waiver program.
The bill would require visitors from the 38 “visa waiver” countries to obtain a visa to travel to the US if they have been to Iran, Syria, Iraq or Sudan in the past five years.
He said the bill is against the rules of free international trade and in violation of basic human rights, as it seeks collective punishment of nations. Ansari described the bill as a big negative sign to Iranians and against the spirit of the nuclear agreement.
Asked about the latest developments concerning Syria, he said Iran's advisory support for Syria will continue, based on the official request of Syrian government. On the political process to find a solution to the Syrian conflict, the spokesman said the next rounds of Vienna peace talks should prepare the ground for negotiations between the Syrian government and opposition groups to get Syria out of the current situation.
The two previous rounds of talks were held in October and November to work out a peace plan that includes a ceasefire in Syria.
Ansari said Iran's participation in the next round of the talks, likely to be held in New York on December 18, depends on the result of efforts to distinguish terrorist groups from opposition groups.
