As the USA sanctions bite, domestic pressure is increasing on Rouhani to demonstrate that Iran can still benefit from an agreement based on providing it with economic opportunities in exchange for limiting nuclear development.
Iran's announcement on Wednesday, related to curbs on its stockpiling of nuclear materials, was in response to US sanctions imposed following President Donald Trump's withdrawal of the United States from the accord with Tehran a year ago.
"The Iranians have used the proxies in the region to dominate and control the Middle East which is their ultimate objective", Keane continued.
According to a senior European diplomat, Pompeo chose to make the last-minute change because leaders from the European Union were already planning to meet to discuss recent developments in Iran.
But she noted that the deal stands a chance if a joint effort is made along with other signatories of the agreement, including China and Russian Federation.
"We are very anxious about a conflict, about the risk of a conflict ... of an escalation that is unintended", Britain's Jeremy Hunt told reporters in Brussels before talks with Pompeo.
At least one, British Foreign Secretary Jeremy Hunt, said he feared that unintentional escalation from the U.S. and Iran could spark a conflict - an unusually bold statement that appeared to assign equal culpability to Washington and Tehran.
So we will see during the day how and if we'll manage to arrange a meeting.
British Foreign Secretary Jeremy Hunt called for "a period of calm".
French Foreign Minister Jean-Yves Le Drian joined the criticism of the United States saying Washington's move to step up sanctions against Iran "does not suit us". Another key accord, the Intermediate-Range Nuclear Forces treaty, just collapsed, with the United States pulling out over charges that a new Russian missile system violated it. Because if Iran becomes a nuclear power, its neighbors are likely to want to become nuclear powers.
The US and Russian Federation are at loggerheads over a number of global issues including Venezuela, where Pompeo has led US calls to demand that Moscow stop backing President Nicolas Maduro, a leftist whom Washington is trying to oust. "We share the same threat assessment", he said. After attending talks, he'll head to Russian Federation.
Pompeo also discussed reported attacks on several oil tankers off the coast of the United Arab Emirates on Sunday. "We have been requested by the UAE to provide assistance in the investigation, which we are very glad to do".
Asked if he himself believed there was the possibility of an Iranian role, Hook had no comment.
Last week, the USA imposed new sanctions on four Iranian metal sectors in the latest component of President Donald Trump administration's "maximum pressure" campaign on Tehran after sending a carrier strike group and a bomber task force to the region in response to unspecified threats from Iran.
"That's why France is remaining and will remain a part of it and I deeply hope that Iran will remain".
