He made the remarks at a joint news conference with his Turkish counterpart Mevlut Cavusoglu after their meeting in Beijing. Cavusoglu kicked off a two-day visit to China on Thursday.
The Joint Comprehensive Plan of Action, also known as the Iran nuclear deal, is a hard-won achievement of multilateralism, and should be maintained by adhering to principles, dialogue and cooperation, Wang said.
Earlier, The spokesman for the Atomic Energy Organization of Iran (AEOI) Behrouz Kamalvandi, said the country will soon start re-building the Arak heavy water reactor once China finishes examining the last phase of the re-designing process.
He said that new work would begin on the nuclear program on the orders of Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei.
“Currently the Leader has ordered that the programs be carried out within the framework of the JCPOA. Once he gives the order we will announce the programs outside of the JCPOA for reviving Fordow,” he added.
Regarding activities at Natanz nuclear facility after any collapse of the JCPOA, Kamalvandi said new advanced centrifuge machines would be installed at the site.
Under the JCPOA, the Fordow plant was to stop enriching uranium and be converted into a nuclear, physics and technology center.
Recently, the head of the AEOI, Ali Akbar Salehi, said the country has begun work to prepare the infrastructure for building advanced centrifuges at the Natanz enrichment facility, while respecting its commitments under 2015 nuclear deal.
On May 8, US President Donald Trump announced Washington's pullout from the nuclear deal, vowing to reinstate nuclear sanctions on Iran and impose “the highest level” of economic bans on the Islamic Republic.
Iran has said it will remain committed to the deal for the time being, pending negotiations with other signatories to the JCPOA to see if Iran’s interests would still be protected under an accord without the US.
