Iran's foreign minister has held talks in China as he began a diplomatic tour with the remaining signatories of a multinational nuclear deal following the recent U.S. withdrawal from the landmark 2015 pact.
Part of the flaw with the Iran deal that President Trump rejected was it enticed Europe and the United States into economic relations with Iran that would work against holding the country accountable for violations of the agreement, Bolton said.
"The ultimate goal of all these negotiations is to obtain assurances that the interests of the Iranian people, which are guaranteed by the Joint Comprehensive Plan of Action, will be protected", Zarif said.
Bolton expressed optimism that European allies will follow Trump's lead and exit the deal, despite the assertions of the leaders of France, the United Kingdom, and Germany that they intend to remain in the agreement.
Trump directed his administration to "immediately begin the process of re-imposing sanctions" related to the deal, a White House statement said.
Britain, France and Germany were to press Iran later on Tuesday to stay in the nuclear accord which US President Donald Trump abandoned last week and which has left Europe with few ways of keeping the accord's benefits flowing to Tehran.
In the past week, it has slapped a new series of sanctions against Iran.
On Sunday, U.S. Secretary of State Mike Pompeo said Washington still wants to work with Europe to counter Iran's "malign behavior" and was working hard to thrash out a more wide-ranging deal with its European partners.
Heiko Maas, the German foreign minister, said he feared that European Union negotiations with Mr Zarif and later with...
Le Drian expressed France's "determination to fight" so that the US decisions don't hurt those companies that have invested in Iran.
He said he was "ready for all options", adding: "If the nuclear deal is to continue, the interests of the people of Iran must be assured". "We will try to uphold our side of the bargain".
"Let's not fool ourselves that are that dozens of things we can do", said a second senior European diplomat.
The accord lifted worldwide sanctions on Iran in 2016 in return for Tehran shutting down its capacity, under strict surveillance by the United Nations nuclear watchdog, to stockpile enriched uranium for a possible atomic bomb.
Tehran has expressed its opposition to Trump's move.
The minister echoed calls from Chancellor Angela Merkel and other leaders that Iran should agree to a broader deal that went beyond the original accord and included Iran's "problematic role in the region".
"The Europeans have between 45 and 60 days to give the necessary guarantees to safeguard Iranian interests and compensate the damages caused by the U.S. pullout", Icana.ir reported. "We don't have much to threaten the Americans".
