Iranian Foreign Ministry spokesman Saeed Khatibzadeh stated in his weekly press conference that the IAEA chief's Saturday trip to Iran was in continuation of the talks in Vienna. 

He added that Iran would cooperate with the UN nuclear watchdog based on the joint statement issued on Saturday, adding that Iran responded to the IAEA's questions. 

Khatibzadeh confirmed that closing the IAEA’s open issues and the potential deal in Vienna were directly linked. 

Regarding the Russian foreign minister’s remarks on the effect of anti-Russian sanctions on Moscow-Tehran trade, Khatibzadeh revealed that Iran is waiting to hear what was said from diplomatic channels.

He added that the talks are flowing in the correct path, emphasizing that Iran's peaceful nuclear cooperation should not be limited or affected. 

The diplomat described Russia’s approach in Vienna as “so far constructive”, adding that the teams have gathered together in Vienna to reach a collective agreement.

Khatibzadeh also described China’s position in Vienna Talks as one of the most constructive ones, also pursued in the same path by Iran.

He discussed the possibility of direct talks between Tehran and Washington, highlighting that the US was no longer a part of the JCPOA and the commitments were clear for Iran and the P4+1 if it intends to return to the deal.

A request for direct negotiation would be possible only if Iran knows the reason for such a meeting, he continued.

"We haven’t witnessed any change in US behavior to date," the spokesman noted, adding that Washington has kept up with the maximum pressure against the Iranian people.
