Iranian Leader advisor on international affairs, Ali Akbar Velayati praised the country's "strategic relationship" with Russia when he arrived in Moscow on Wednesday.
"U.S. President Donald Trump unreliable actions made Tehran's close ties with Moscow all the more necessary", Iranian Leader advisor on international affairs noted.
"The relationship between Iran and the Russian Federation is a strategic relationship and in recent years the collective bilaterial and regional relations have expanded," Velayati added.
Iranian Leader advisor on international affairs said he would deliver messages to Putin from Iran's Leader and Iranian president Hassan Rouhani and that they would discuss the very sensitive global situation.
"Only a strategic and long-term relationship with Russia can continue this cooperation," said Velayati.
Iranian Leader advisor on international affairs was also due to meet Russian Energy Minister Alexander Novak in Moscow.
Asked about Israeli Prime Minister Benjamin Netanyahu's visit to Moscow, Velayati said: "His presence or absence in Russia has no effect on our strategic mission in Moscow."
Israeli Prime Minister Benjamin Netanyahu was also visiting Moscow on Wednesday.
It is his third trip to Moscow this year.
US President Donald Trump announced on May 8 that Washington was walking away from the nuclear agreement, officially known as the Joint Comprehensive Plan of Action (JCPOA), signed between Iran and the five permanent members of the United Nations Security Council -- the United States, Britain, France, China and Russia -- plus Germany in 2015.
Tehran has conditioned its stay in the deal to practical European strides to make sure Iran’s dividends from the deal would not be affected when US sanctions "snap back" in August.
