But President Donald Trump said the agreement did not go far enough.
France and other Western allies have been critical of Washington's plan to reimpose sanctions on any companies doing business with Iran.
Iranian Foreign Minister Mohammad Javad Zarif has embarked on a whirlwind diplomatic tour to gauge worldwide readiness to guarantee Iran's interests if it decides to remain in a nuclear deal after U.S. withdrawal.
After the U.S. departure from the nuclear deal, Iran is making sure that the deal survives under all circumstances.
He added: "As the president of the republic has said, we are ready for all option (s)".
According to Zarif, the objective of his trip is to get guarantees from the other participants of the nuclear deal that the interests of Iran will be protected.
Zarif is scheduled to talk with Russian Federation on Monday about the nuclear deal.
European governments tried for months to persuade Trump to stick with the deal but failed, and now fear it will raise the risk of conflict in the region.
This echoes statements from China, which has also said it wanted to continue normal business ties with Iran and is now financing multi billion dollar infrastructure and electricity projects in the country.
"They have faith Russian Federation and China will stand by their side as some of their closest allies and biggest supporters", added Basravi.
Iran has threatened to resume "industrial scale" uranium enrichment "without any restrictions" if it does not get guarantees that the trade ties which have been established with Europe since the deal was signed will be maintained. It is the second leg of his tour during which he is to sit down with officials from 5 states in the JCPOA to discuss how Iran's interests under the deal can be guaranteed. They will also discuss overcoming Israeli resistance to Iran's military presence in Syria, TASS reported Monday.
Zarif made no mention of the flare-up with Israel, but said the country had the right to defend itself, particularly in the light of the eight-year war with Iraq that began when the regime of Saddam Hussein invaded Iran in 1980.
Furthermore, the United Nations and the European Union have also warned Washington against any bid to sabotage the deal.
Mohammad Ali Jafari, head of the Revolutionary Guards, said the country could not rely on the West.
The sentiment was echoed on the streets.
"Officials shouldn't trust France and Britain. They will never abandon the United States for us", said housewife Poormoslem at a protest against Trump on Friday.
While Tehran was shunned by the global community in the 1990s, Moscow agreed to resume the construction of the Bushehr Iranian nuclear plant that Germany had abandoned.
