The United States blacklisted Iran’s state broadcasting authority, Internet-policing agencies and
a major electronics producer on Wednesday, an action that widened the American sanctions
effort to pressure the Iranian government over not only its disputed nuclear program but also
over the stifling of domestic dissent and access to information.
A statement by the Treasury Department also announced the formal start of tightened
restrictions, under a law passed last year, meant to severely inhibit Iran’s already weakened
ability to repatriate earnings from the sale of oil, its most important export.
The new sanctions targeted Islamic Republic of Iran Broadcasting, which is responsible for
broadcast policy in Iran and oversees production at Iranian television and radio channels.
