(afp) -- "The failed experience of sanctions and coercion brought their previous administrations to the negotiating table," Rouhani told parliament in a televised speech.

"If they want to go back to that experience, definitely in a short time -- not weeks or months, but in the scale of hours and days -- we will return to our previous situation very much more stronger."

Rouhani said his US counterpart Donald Trump had shown the world he was "not a good partner" by threatening to tear up a 2015 nuclear deal.

"In recent months, the world has witnessed that the US, in addition to its constant and repetitive breaking of its promises in the JCPOA (nuclear deal), has ignored several other global agreements and shown its allies that the US is neither a good partner nor a reliable negotiating party," Hassan Rouhani told parliament.
