As 60 days of peace negotiations between the US and Iran continue, Tehran appears to have won significant concessions from Washington. Chief among those is the waiving of sanctions on Iranian oil exports. US sanctions have been in place for decades, cutting Iran off from mainstream global oil markets and forcing it to sell its oil to China at discount rates. The US says the other side of the deal is that Iran will allow international inspectors access to its nuclear program – Tehran though says it has made no such commitment.
