Rafsanjani made the remark during a meeting with new Japanese Ambassador to Iran Hideaki Domichi.
He stressed the role of Iraq's neighboring states in establishing peace in the war-torn country.
Rafsanjani added that instability and insecurity in Iraq has left negative effects on the neighboring states.
Due to the Iran-Iraq long borders, Iran has incurred extensive damage in this regard, he said.
He called for holding of timely elections in Iraq and safeguarding of the country's territorial integrity.
He said that withdrawal of foreign powers and refraining from any action which fan the flame of tribal, regional and internal rivalries was the main factor for the establishment of security in the region.
Foreign occupiers in Iraq seek to secure their own interest by fanning the flame of tribal and ethnic discord between Shiites and Sunnis, he added.
The EC chairman said that the main reason behind the US attack on Iraq was to dominate its energy resources in Persian Gulf region.
The US was about to take over the whole region through military attack but the invasion only led to increasing energy prices, the official said.
He also expressed satisfaction with bolstering of Iran-Japan ties, stressing further cooperation between the two countries based on mutual interests.
He underlined the importance of Japan's position in Iran's foreign policy, saying that boosting bilateral energy cooperation has opened a new chapter for consolidation of Tehran-Tokyo relations.
The Japanese ambassador, for his part, expressed his nation's and government's readiness to expand cooperation with Iran.
He said the peace and stability of the region was of high importance, calling on Iranian officials to play their constructive role in this connection.
