The US administration is just one step away from passing another round of strict commercial sanctions against Iran, which is yet to respond to the UN call for nuclear activities suspension. US is now proposing to penalize all the global companies which deal with Iran, by not allowing them access to US market and US technologies.
That is a big blow indeed and many Russian , Chinese and developing world companies might instantly cut down their business relationship with Iran.
But Iran says that the sanctions may not have any impact on it at all since most of the global companies are not doing any business with it even today.
