US Secretary of State Mike Pompeo also threatened Iran with the "strongest sanctions in history" if it did not comply with a list of steep demands, including ending uranium enrichment.
Rouhani appreciated efforts by China and Russia to preserve the nuclear accord, saying, "All signatories to the JCPOA have a responsibility regarding the commitments of removing sanctions under the JCPOA, and also based on Resolution 2231 of the UN Security Council and Article 25 of the Charter of the United Nations are responsible to help full implementation of the JCOPA and prevent any move that poses an obstacle on implementation of the JCPOA."
He also noted that the remaining parties to the deal have "a limited opportunity" to provide the "necessary guarantee in action to help implement all the agreed conditions in the JCPOA and continue being a party to this agreement."
"Definitely, the US has monitored the reactions to its withdrawal from the JCPOA and considers the lack of response to its unilateral withdrawal as not being costly, which will have very bad consequences for the international community," he pointed out.
Elsewhere in his address, the Iranian president warned of the threat posed by terrorism, separatism and extremism to the world, calling for an increase in intelligence exchange between regional countries in a bid to weaken terrorist groups.
The Islamic Republic, he said, "has invaluable experience in curtailing and weakening of extremist and terrorist currents, an example of which is cooperating with the government of Iraq and Syria in fighting [Daesh] terrorist."
