Foreign Ministry spokesman Hossein Jaber Ansari said neighboring countries should avoid adventurism, respect each other and be accountable for their stances.
Ansari made the statement on Friday, in response to recent claims that Turkish President Recep Tayyip Erdogan has warned Iran, IRNA reported.
Erdogan reportedly said he has held talks with his Iranian counterpart, President Hassan Rouhani, asking him to avoid repeating the Russian accusations about Turkey's purchase of crude oil from the Islamic State militant group.
Erdogan added that then onwards Iranian officials and certain Iranian news outlets stopped making such allegations.
Ansari said adopting policies, which are in favor of terrorist groups in Syria and Iraq, intentionally or unintentionally, will intensify regional crisis and increase problems for countries pursuing them.
"The Islamic Republic of Iran welcomes change in policies [of some regional countries which are widely known to be helping terrorists] and contribution of all regional states to the battle against terrorism and extremism," he said. "To this end, Iran is ready for cooperation and coordination with neighbors."
Russian Deputy Defense Minister Anatoly Antonov said last Saturday that Moscow has evidence indicating the complicity of Turkish president and his family in the smuggling of oil from territories held by IS.
"Turkey is the main consumer of the oil stolen from its rightful owners, Syria and Iraq,” he said, citing photos showing columns of tanker trucks purportedly loading oil at IS-controlled installations in the two violence-scarred Middle Eastern states before entering neighboring Turkey.
Syria’s military also announced on Saturday that Ankara has recently increased its supplies of weapons to militant groups, claiming they are humanitarian aid.
Turkish opposition daily Cumhuriyet published videos in a June report implicating the Turkish intelligence service in ensuring safe passage into Syria for militants.
