"There is no disruption in exporting Iran's oil," Mehman-Parast told reporters in a press conference here in Tehran on Tuesday, saying that some western states are trying to show that the world countries are reducing their cooperation with Iran in the energy sector.
But he said such antagonistic efforts are destined to failure. "Provoking a negative atmosphere about Iran's oil cooperation with the other countries will actually lead to nowhere."
Iranian Oil Minister Rostam Qassemi had earlier this month announced that despite the international and unilateral sanctions against the country's oil sector, Iran's annual crude exports have reached $60bln.
"This year the situation of (our) oil exports has improved and long strides have been taken for the flourishing of the country's economy," Qassemi said.
"Despite the fact that all countries have mobilized against Iran, the country's oil exports have reached $60bln now," he added.
Qassemi downplayed the effects of sanctions on the country's progress and flourishing, and said enemies should know that Iran is independent from other countries and sanctions have led to Iran's further progress and development.
In the last days of 2011, Washington imposed new sanctions on Iran to penalize countries for importing Iranian oil or doing trade with its central bank.
The US extraterritorial laws and pressures forced the EU member states to ratify in their meeting on January 23 and after months of debates to sanction oil imports from Iran and freeze the assets of Iran's Central Bank within the EU.
The Iranian oil ministry in a statement in late January downplayed the effects of the US and EU's unilateral oil sanctions against Tehran, and said such embargoes will merely harm the European economies and oil consuming countries.
European sanctions against Iran's oil exports will affect the world economy and hurt European and non-European countries, the statement said.
Later, Tehran summoned the ambassadors of Italy, Spain, France, Greece, Portugal and the Netherlands to protest at the EU's unilateral sanctions against Tehran over its peaceful nuclear program, and warned them that it would soon stop oil exports to these countries if they do not reverse their decision.
After the EU's decision to embargo Iranian oil supplies, Tehran stopped exports first to France and Britain and very recently to Greece and Spain. Following Tehran's oil sanctions against the three and its warning to other EU members, oil prices started soaring in the world markets.
Meantime, demand is growing for Iranian crude oil in Asian and African markets after the EU's fresh decision.
Iran is currently supplying 100% of Sri Lanka's oil needs, 51% of Turkey, 25% of South Africa, 13% of Italy, 11% of India and China and 10% of Japan and South Korea's oil demands.
