The United States has imposed more unilateral sanctions on Iran by blacklisting a number of petrochemical companies in the Islamic Republic.The US Treasury Department issued a statement on Friday, announcing sanctions against eight Iranian petrochemical companies. The Treasury Department blacklisted Bou Ali Sina, Mobin, Nouri, Pars, Shahid Tondgouyan, Shazand, Tabriz and Imam petrochemical companies. The US also imposed separate sanctions on Niksima Food and Beverage JLT, a frozen yogurt company based in the United Arab Emirates, saying the company has been engaged in a transaction for the purchase of petrochemical products from Iran. At the beginning of 2012, the US and the European Union imposed new sanctions on Iran’s oil and financial sectors with the goal of preventing other countries from purchasing Iranian oil and conducting transactions with the Central Bank of Iran. The illegal US-engineered sanctions were imposed based on the unfounded accusation that Iran is pursuing non-civilian objectives in its nuclear energy program. Iran rejects the allegations, arguing that as a committed signatory to the nuclear Non-Proliferation Treaty (NPT) and a member of the International Atomic Energy Agency (IAEA), it has the right to use nuclear technology for peaceful purposes. In addition, the IAEA has conducted numerous inspections of Iran's nuclear facilities but has never found any evidence showing that Iran's civilian nuclear program has been diverted to nuclear weapons production.
