Speaking on "Fox News Sunday, " Secretary of State Mike Pompeo said withdrawing from the 2015 accord wasn't aimed at Europeans, but he didn't rule out the USA imposing sanctions on entities that continue to do business with Iran, even as efforts continue to strike a new deal. The foreign ministers of the three European powers will meet their Iranian counterpart in Brussels on Tuesday to discuss a way forward.
Mohammad Javad Zarif's diplomatic tour took him to Beijing at the weekend and will see him visit Brussels later in the week, as the worldwide backers of the 2015 accord scrabble to save it.
He said the deal "is based on the balance of obligations" between Tehran and the opposite side, including the USA, and that after Washington's pullout "this balance is undermined", adding, "We should see how we can secure the interests of the Iranian people". "We will all save it together".
"It is going to be very hard for us to preserve the economic benefits of the Iran deal", one senior European diplomat said.
"I would like to point out that Russian Federation and other participants in the deal - China and the European countries - also have their legitimate interests enshrined in this agreement", he added.
Tehran has expressed its opposition to Trump's move.
Johnson also called on Washington "to avoid any actions that could prevent the remaining parties to the agreement from meeting their commitments under the deal - including delivering sanctions relief through legitimate trade".
Before leaving Iran, Zarif published a government statement via Twitter criticising Trump's "extremist administration" for abandoning "an accord recognised as a victory of diplomacy by the worldwide community".
"I am hopeful in the days and weeks ahead we can come up with a deal that really works, that really protects the world from Iranian bad behavior, " Pompeo said.
"They have faith Russian Federation and China will stand by their side as some of their closest allies and biggest supporters", added Basravi.
But while Pompeo talked up the prospect of renewed coordination with America's allies, another top aide reminded Europe its companies could face sanctions if they continue to do business with the Middle Eastern power.
Iran's Supreme Leader Ayatollah Ali Khamenei has called the United States withdrawal "impudent" and "worthless".
Basravi said the Rouhani government's "political health. hangs in the balance" as the administration has "married itself to this deal and championed it as the answer to all" of the country's economic woes. Then he left Moscow for Brussels where he is slated to meet with the foreign ministers of UK, Germany, and France as well as the EU High Representative Mogherini.
