What did sanctions do to Iran’s economy?

While the US government officials had previously said that they have taken a commitment from 8 important international oil and gas companies, including Eni Italy, to gradually and eventually stop their activities in Iran, reports from Italian sources show that Eni In the fiscal year 2010, 888 million dollars were traded with Iran. In a report published on April 23, 2011 (April 12, 2011), the Italian language internet site Bursa Italiani wrote: The Italian oil and gas company Eni bought oil equivalent to 888 million dollars from Iran exactly in the year when it should have intensified its strategic exit from Tehran, and all this amount was deposited into the account of the National Iranian Oil Company. This Italian source then informed about it. Given that Eni has doubled its crude oil import from Iran in 2010 compared to 2009. Bursa Italiani writes: In 2010, the Italian Oil and Gas Company imported about 1.6 million tons of crude oil from Iran to Italy, which has doubled compared to the crude oil imported from Iran in 2009, which was equal to 980 million tons. . Bursa Italiani continues: There are other cases that show that in 2010, Eni company bought 2 million tons of Iranian crude oil from different traders worth more than one billion dollars. While in 2009 Eni had bought less than 150 million dollars worth of Iranian crude oil from other traders, Eni is one of the largest Italian oil and gas companies headed by Paolo Scaroni. On September 30, 2010, US Deputy Secretary of State James Steinberg said that the US has exempted 4 European companies from punishment due to their commitment to stop investing in Iran, one of which is the Italian company Eni. But the statistics mentioned in this report show that he did not attach any importance to the promise he made to America. Experts say that the most important lever that European companies use to refuse the implementation of American requests is that the laws of the European Union and the resolutions of the Security Council do not prohibit the purchase of oil from Iran.
