Iran ceased to respect in May certain commitments contained in the nuclear deal reached in 2015 with the world powers, after the United States withdrew unilaterally from the agreement in 2018 and strengthened the sanctions imposed on Tehran.
"Clearly, Iran can not stick to this agreement unilaterally," President Hassan Rouhani told Russian, Chinese and other Asian leaders at a conference in Tajikistan.
Rouhani did not mention the oil tanker incident this week in his speech at the Conference on Measures of Interaction and Building Confidence in Asia, held in Dushanbe, the capital of Tajikistan.
"It is necessary that all parties to this agreement help to restore it," he said, adding that Iran should receive "positive signals" from other signatories of the pact, including Russia, China, Britain, France and Germany.
He did not give details of the actions that Iran would undertake nor on the positive signals that Tehran wanted to see.

"We believe the only sensible decision is that all the participants in the agreement honor their commitments," Putin told the conference.
Tehran said in May that Iran would start enriching uranium at a higher level unless world powers protect its economy from US sanctions within 60 days.

France and other European signatories to the nuclear deal aimed at curbing Iran's nuclear work have said they want to save the deal, but many of their companies have canceled their agreements with Tehran, under the pressure from the United States.
