US President Donald Trump is going to continue his predecessor Barack Obama’s sanctions policy against Iran, but the administration is going to earn nothing through putting more pressure on Iran, says a commentator.

Mostafa Khoshcheshm, journalist and political commentator, told Press TV on Wednesday that “Tehran is basically sending this message to Donald Trump that he needs to change tactic and that he would not earn anything better even if he tries to exert more pressures on Tehran.”

In an interview with the BBC on Tuesday, Iranian Foreign Minister Mohammad Javad Zarif praised the European signatories to the nuclear agreement for defying US President Donald Trump’s pressure and standing by the Joint Comprehensive Plan of Action (JCPOA) -- a binding international agreement.

Khoshcheshm also said, “He (Zarif) is trying to do what the Iranian administration has long been trying to do ever since Donald Trump came to power by trying to make him (Trump) understand that he may not continue the same kind of tactic that was under way by Obama that is the engagement policy in order to get more concessions from Tehran.”
