Under the terms of the agreement, reached under Mr Trump's predecessor Barack Obama, Iran agreed to limit its controversial nuclear programme in return for an easing of economic sanctions. They are not just about schmoozing - they are often about serious matters of policy and in this case, that means the focus will be the fate of the Iran nuclear deal, which President Donald Trump described Tuesday as "ridiculous" and "insane" and which President Macron is still looking to salvage.

In one of his final appearances of the trip, he expressed pessimism about the future of the Iran nuclear deal, saying he believed Trump may end up pulling out of the agreement.

Though his suggestion of a new, separate agreement appeared to surprise Macron's own European allies, Trump seemed at least somewhat interested in the French president's blueprint, calling it a "new deal" with "solid foundations". Dan Sullivan, R-Alaska, said the nuclear deal was not supported by the Congress. The committee's senior Democrat, Sen. Addressing the inaugural function of a programme in the north-west city Tabriz, Rouhani said that some countries think that White House should decide regarding north Asia, they also think a tyrant government should also dominate the region.

"When Iran agrees to accept constraints on its nuclear program that enhances global security and enhances Iran's ability to work with other nations. We have to keep our eyes wide open to the new risks, right in front of us".

He called for greater efforts on climate change - because "there is no planet B" - as well as "a more effective, accountable, and results-oriented multilateralism". He has recently intensified his rhetoric, demanding to "fix" the deal and threatening to pull out of it otherwise.

French President Emmanuel Macron addressed a joint session of Congress on Wednesday.

"We wrote these rules", Macron said.

Iran was one major issue up for discussion and President Trump claims Mr Macron is now viewing the situation "differently" from when he first arrived. "The deal is working", said Federica Mogherini, the European Union's foreign-affairs chief, in January.

In his speech to Congress, Macron pushed the US to consider rejoining the Paris climate change agreement, which Trump announced his country would leave last year.

His wife won't let him get handsy (or even hold hands) with her, so Donald Trump is all over Emmanuel Macron - grooming him much like a gorilla would, says a top body language expert.

"Commercial war is not the proper answer", Macron said.

"I'm sure one day the U.S. will come back again to join the Paris agreement", Macron predicted.

"We should not abandon it without having something substantial and more substantial instead", he told Congress. And I want everybody to understand, I am not neutral in that contest.

The head of Iran's nuclear agency expressed the hope that the United States "comes to its senses", but warned that Tehran's response will be "astonishing" if the nuclear deal is scrapped.

French President Emmanuel Macron gestures as he is introduced before speaking to a joint meeting of Congress on Capitol Hill in Washington, Wednesday. "You can play with fears and angers for a time, but they do not construct anything".

"Our strongest beliefs are challenged by the rise of a yet unknown new world order".
