West must remember about the consequences of its last mistakes towards Iran, Secretary of the Iranian Supreme National Security Council and chief negotiator on nuclear issues Saeed Jalili, was quoted by ISNA news agency referring to the al-Alam News Network as saying.
"Western countries should not make previous mistakes in their calculations and follow their way," Jalili said.
He said that any new sanctions of the West against Iran will be worth much.
In June 2010 the U.N. Security Council adopted Resolution 1929, enacting new sanctions against Iran over its refusal to stop enriching uranium. Later, the U.S. Congress and foreign ministers of all EU countries approved the imposing of additional unilateral sanctions aimed mainly against the energy, banking and financial sectors of Iran.
The restrictions imposed by the EU include the ban on the sale of equipment, technologies and services in Iran's energy sector. The oil processing industry is among these measures. New investments in Iran's energy sector as a whole were also banned. The production capacity of the the country is decreasing. Iran can not effectively increase production due to the lack of investments.
Several European banks refuse from opening a credit line for Iranian citizens. So, they have to pay in cash. Moreover, the sale of certain goods to Iran was banned.
