The sanctions proposed in Saturday's resolution will impose an embargo on all conventional weapons sold by Iran and freeze the assets abroad of Iran's state-owned Bank Sepah, which the US has already done, isolating it from international financing.
The text calls, rather than orders, nations and international financial institutions to restrict new grants, credits and loans to Iran, which the World Bank or the IMF are unlikely to issue.
