Saudi Arabia and other Arab countries do not support but oppose Iran's nuclear program.

Pakistan might enjoy good 'brotherly' relations with Iran but I think Pakistani establishment does not trust Iran remember Iran naming Dr.AQ Khan in nuclear proliferation and presenting even the cheques paid to us?

Our interests in Afghanistan also do not converge with those of Iran.

Iran is just an observer in SCO and not a permanent member yet.
