Rouzbeh Parsi was quoted by CNBC:

Rouzbeh Parsi, Iran expert at the EU Institute for Security Studies, told CNBC.com that while the sanctions may well affect the economy, the effect on the nuclear program itself could be limited. Iran can continue to sell hydrocarbons to Asian markets, and what resources it has will continue to be directed towards its nuclear program, Parsi said. CNBC.com
