The Iranian foreign minister is also set to hold talks with Russian head of foreign affairs Sergei Lavrov in Moscow on Monday and foreign chiefs from the United Kingdom, France and Germany, as well as Federica Mogherini, High Representative of the European Union for Foreign Affairs and Security Policy, in Brussels on Tuesday.
Mr Hook argued the US President's decision will stand in the pursuit of a new deal with Iran that will prevent the rogue state developing nuclear weapons. "The agreement against nuclear weapons in Iran is an agreement that certainly has weaknesses, but an agreement that we should stand for".
The EU insists the deal is working, pointing to repeated United Nations inspections verifying the Islamic Eepublic's compliance with its side of the bargain, and Mogherini's spokeswoman Maja Kocijancic told AFP ahead Zarif's arrival that "we must do our utmost to preserve it".
When pressed by CNN on whether the administration would sanction European firms that continue to do business with Iran, Bolton said, "I think the Europeans will see that it's in their interest ultimately to come along with us".
By reimposing nuclear sanctions on Iran and withdrawing from the Joint Comprehensive Plan of Action, otherwise known as the Iran Nuclear Agreement, President Trump has put our nation on a risky path. Among them is Total's $5bn project to develop the world's largest gas field, South Pars, where the French oil company has a 50.1 percent stake.
British counterpart Johnson said the "UK and France are determined to conserve the essence of the Iran nuclear deal".
Cars of the Iranian delegation are parked outside a building of the Diaoyutai state guesthouse in Beijing on May 13, 2018.
Zarif departed for Beijing in the early hours of Sunday before heading to Moscow and Brussels to hold meetings with the remaining parties to the 2015 agreement, his spokesman said. "When I make promises, I keep them".
We too must be ready to abandon some of our commercial interests in exchange of preserving our security and stability. And this is what he discussed with President Macron.
In Berlin, Economy Minister Peter Altmaier said Germany was ready to give help to its affected firms, including legal advice, to continue doing business in Iran.
Tehran said it is too early to voice an opinion regarding the European companies' contracts in Iran such as those of Total and Renault, considering the six-month deadline which the USA president talked about.
Pompeo was in Pyongyang on Tuesday when Trump made the announcement and senior State Department officials said the secretary will try to persuade allies in Europe, the Middle East and Asia to pressure Tehran to return to talks.
As those sanctions kick in, it will have an even broader effect as well, Bolton said.
