"China, India, Japan, South Korea and other countries that were granted waivers from America to import Iranian oil are not willing to buy even one barrel more from Iran," Amir Hossein Zamaninia, Iran's deputy oil minister for trade and international affairs, was quoted as saying by the Oil Ministry's news agency SHANA.
However, without giving details, Zamaninia said: "Despite US pressures on Iranian oil market, the number of potential buyers of Iranian oil has significantly increased due to a competitive market, greed and pursuit of more profit."
The 180-day exemptions were also granted to Italy, Greece, Taiwan and Turkey. Washington seeks to bring Iranian oil exports to zero in order to curb Tehran's missile and nuclear programmes and counter its growing military and political influence in the Middle East.
