Iranian Foreign Minister Mohammad Javad Zarif is visiting Beijing to meet with Chinese leaders following U.S. President Donald Trump's decision to pull out of the landmark 2015 nuclear deal.
"If the remaining five countries continue to abide by the agreement, Iran will remain in the deal despite the will of America", he continued, according to Reuters.
As he arrived in Beijing, Zarif said Tehran was "ready for all option (s)", according to the semi-official ISNA news agency.
"Considering the fact that the European Union member states have made the most requests that after America's withdrawal it wants to stay in the JCPOA, we should see how these countries ensure that the interests of Iran will be guaranteed despite America's pullout", he stated.
Zarif and Mogherini also conferred on plans and arrangements for a Tuesday meeting in Brussels between them and the three European countries foreign ministers, FNA said.
Iran has said it would remain in the JCPOA for now, pending negotiations with the other signatories in the coming weeks before making a final decision.
"I hope and believe that these visits to multiple countries will improve countries', including China's, understanding of Iran's position", Wang said.
"Iran's interests in important areas and issues relevant to the JCPOA, like oil, gas, and petrochemicals sales, as well as banking relations should be clearly and explicitly defined and guaranteed", Rouhani said.

This is Australia's worst mass shooting since a massacre in Port Arthur, Tasmania, claimed the lives of 35 people in 1996. Three guns - all registered to Peter Miles - were found at the house.
Before leaving, Zarif published a government statement on his Twitter page, slamming Trump's "extremist administration" for abandoning "an accord recognized as a victory of diplomacy by the global community".
China offers Iran a valuable alternative to trade with the USA and Europe.
While announcing his decision, Trump called the agreement "defective at its core", claiming that after the lifiting of the sanctions Tehran "used its new funds to build nuclear-capable missiles, support terrorism and cause havoc throughout the Middle East and beyond".
Trump hit back Saturday evening, tweeting that the accord had failed to contain Iran's militarism.
Foreign Ministry spokesman Geng Shuang said Wednesday that China would "carry on the normal and transparent pragmatic cooperation with Iran".

Iran's main concern is that renewed USA sanctions will have a far-reaching impact on the willingness of non-American companies and banks to deal with Iran, crippling its trade, oil exports and an already strained economy.
