The Economic Cooperation Organization (ECO) says it will not support anti-Iran sanctions, adding that such measures have no effects on the country's economy, Press TV reported.
"This organization as an economic institute will not support the imposition of sanctions against the Islamic Republic of Iran," IRNA quoted ECO Secretary General Mohammad Yahya Maroufi as saying on Sunday.
"These sanctions have no effect on Iran's economy, and this country along with other ECO member states will continue to progress," he said.
Accusing Tehran of pursuing a military nuclear program, Western countries led by the US have imposed unilateral anti-Iran sanctions in addition to the UN Security Council resolution adopted against the country in June.
Tehran rejects the accusations, arguing that as a member of the International Atomic Energy Agency (IAEA) and a signatory to the Nuclear Non-Proliferation Treaty it has the right to peaceful nuclear energy.
The allegations come despite assurances from the IAEA on the non-diversion of Iran's nuclear activities.
Maroufi further said that the ECO is conducting a study on the effects of the global economic crisis on its member states.
Initial results of the study show that ECO member states have not been largely affected by the global recession, the secretary general added.
ECO is an intergovernmental regional organization established in 1985 to promote economic, technical and cultural cooperation among the member states.
Iran, Turkey, Pakistan, Azerbaijan, Afghanistan, Tajikistan, Kazakhstan, Kyrgyzstan, Uzbekistan, and Turkmenistan are currently members of the ECO.
