Russian FM Sergey Lavrov and his Iranian counterpart Mohammad Javad Zarif will meet on Monday in Moscow to discuss the preservation of the Iran nuclear deal following President Trump's withdrawal and renewal of United States sanctions.
Mr Johnson revealed on Monday that he would discuss ways to protect them during a meeting with fellow foreign ministers from France and Germany on Tuesday.
Upon arrival Araqchi held talks with Helga Schmid, secretary-general of the European External Action Service.
"Today we hope to see how we can use the available mechanisms not to allow the undermining of this important document with the participation of European Troika, China, Russia, Iran and European Union", he stressed.
Trump has said the United States would be reinstating the anti-Iran bans lifted under the JCPOA and also slapping the "highest level" of economic sanctions on Tehran, prompting anger among other parties to the Iran deal, which unanimously denounced Washington and vowed to stay committed to their side of the deal.
"It is a trade-off and a sensible trade-off and... it is the only really workable way we can see to stop Iran getting a nuclear weapon".
The meeting comes amid fears that European companies may face reprisals from the USA for breaching American sanctions by continuing to operate in Iran.
Europe sought on Tuesday to find a way to save the Iran nuclear deal without the United States but was short on details about how the accord could survive the reimposition of US sanctions ordered by President Donald Trump.
In a meeting in Beijing over the weekend, Chinese Foreign Minister Wang Yi promised Zarif that Beijing would take "continue to work to maintain the deal".
"The Russian Federation and other participants of this deal - China, the Europeans - also have legitimate interests that are enshrined in this agreement and approved by the U.N. Security Council", Lavrov said.
"Unfortunately, protesting against global rules and laws has become a habit for the U.S. government", the Iranian foreign policy chief said.
This, along with its diplomatic moves to orchestrate an end to the conflict, has put Moscow at loggerheads with the United States and Europe, which have intervened against the regime.
Putin stressed that Russian Federation will try to maintain the nuclear agreement.
