Iranian President Hassan Rouhani said on Sunday that Tehran will not hold talks with the United States under pressure, adding that Iran's assistance is necessary for the sake of security in the Middle East.

Rouhani said in a televised press conference that if the United States returned to the nuclear deal and lifted sanctions on Iran, then it would be possible to sit at the negotiating table with it, believing that Washington realized that it had miscalculated in dealing with Iran.

He added that his country would not submit to pressure on negotiating the nuclear program, and considered that the security and economic indicators showed that Iran had passed US pressure. 

The Iranian president emphasized that "establishing peace and stability in the sensitive Middle East region and in the Gulf is impossible without Iran's help."

He revealed that his country's relationship with the UAE is continuing, and that negotiations with it have not stopped, indicating that the level of representation in it changes according to circumstances.

Last January, Rouhani considered that European countries are responsible for any breach that violates the nuclear agreement, and specified his country's condition to fulfill its obligations under this agreement, stressing that Tehran does not seek at all to acquire a nuclear weapon.

He said that those European countries - referring to Britain, France and Germany that are still involved in the nuclear deal - bear the consequences of any decision they take or violate the terms of the nuclear agreement.

In response to what it considers to be a failure by France, Germany and Britain to implement the terms of the 2015 nuclear agreement, Iran gradually reduced its obligations under this agreement, which guaranteed it the lifting of sanctions in exchange for curbing its nuclear activity, after Washington withdrew from it and imposed severe sanctions on Tehran.
