Ali Akbar Velayati, a senior adviser to Iran's supreme leader, Ayatollah Ali Khamenei, hailed his country's "strategic relationship" with Russian Federation ahead of a meeting with President Vladimir Putin in Moscow.
Speaking to reporters upon his arrival in Moscow on Wednesday, Velayati pointed to Netanyahu's upcoming visit to the Russian Federation and said, "He is an itinerant person who travels to somewhere in the world every day".
Both countries emphasized continuation of Astana talks between Iran, Russia and Turkey, he said.
Moscow has teamed up with Tehran to shore up Syrian President Bashar Assad's government, but their interests do not always converge.
Velayati is in Russian Federation as a special adviser to President Hassan Rouhani and will travel to China on Friday, so the same request has also been made to Chinese authorities, the foreign ministry said in a statement.
Iran has also made moves to align closer with China, with Velayati expected to visit Beijing in the near future, Reuters reports.
Velayati is among special envoys that Iran is sending to various countries in response to the USA withdrawal earlier this year from the 2015 nuclear deal.
Iranian Foreign Ministry Spokesman Bahram Qassemi said on Tuesday that Velayati's visit was part of efforts to make Iran's stance clear after the USA pullout from the JCPOA signed between Tehran and the P5+1 group of countries in 2015. However, Secretary of State Mike Pompeo said on Tuesday the United States might consider requests from some countries to be exempted from sanctions.
Apart from the United States, the other signatories to the 2015 Iran nuclear deal - Russia, China, Germany, France and Britain - have said they still support the accord.
But European firms are reluctant to risk far-reaching U.S. financial penalties they would face for doing business in Iran.
Russian President Vladimir Putin has received the Iranian leader's top adviser hours after conferring with the Israeli prime minister about Iran's presence in Syria.
He added that cooperation in the region between the resistance front led by Iran and Russian Federation against terrorism and its supporters in Syria and other regional countries was indicative of an exemplary, strategic and long-term partnership between the two countries.
