Rouhani spoke after returning to Tehran on Thursday from NY, where he addressed the UN General Assembly.
Rouhani noted that the United States wanted to turn the UNSC session against Iran by changing the agenda of the meeting, while something different finally turned out and the session instead focused on non-proliferation.
The Europeans highlight that United Nations inspectors have repeatedly found that Iran is in compliance with the 2015 deal, under which it scraps the bulk of its nuclear program in return for sanctions relief. In November, the U.S.is expected to pass additional embargoes targeting oil and shipping industries, the BBC reports. In the United State's estmation, he said, "might makes right".
Iran's president said on Thursday that the U.N. Security Council meeting chaired by President Donald Trump the previous day reflected America's increasing isolation among the global community.
A chief catalyst was Trump's decision to withdraw from the Iran nuclear deal even as world powers urged the U.S. to stick to its mandate.
Asked about those nations' back channel to continue economic relationships with Iran, Pompeo said: "To continue to create mechanisms to fund the world's largest state sponsor of terror is disastrous policy and I hope they will reconsider it".
Also defending the deal that was endorsed in a Security Council resolution, British Prime Minister Teresa May said it "remains the best means of preventing Iran from developing a nuclear weapon".
The meeting was attended by the European Union "Big Three", i.e. Britain, France and Germany (the E3), plus Russian Federation and China.
The meeting between the remaining parties to the Iran nuclear deal came after bilateral talks between Zarif and Mogherini, during which the latter said Europe is finalizing its offers to meet the Islamic Republic's demands in a bid to save the JCPOA.
Trump has warned countries they had to choose between doing business with the U.S., the world's largest economy, or Iran.
This was an apparent response to a speech delivered by Mr Rouhani days earlier, in which he said: "Do not play with the lion's tail or else you will regret it".
The Belgian premier, for his part, emphasized on his country's determination to expand and deepen relations with Iran, and said Belgium is "a supporter of multilateralism" and does not hesitate to try to save the JCPOA.
