The US has asked all countries, including India, to stop all oil imports from Iran by November as it ruled out any exemption to India and Indian companies from its reimposed Iranian sanctions regime for them carrying out any transaction with Iran.
On China and India, yes, certainly, a state department official told reporters when asked if the US has told all countries, including India and China, to stop all their imports of Iranian oil by November 4. He said Indian and Chinese companies would be subject to the same sanctions as those in other countries. Given the huge energy needs, India and China are major importers of Iranian oil. Their (India and China) companies will be subject to the same sanctions that everybody else's are if they engage in those sectors of the economy that are sanctionable, where there were sanctions imposed prior to 2015.
And yes, we will certainly be requesting that their oil imports go to zero. Without question, the state department official said on condition of anonymity.
