"The U.S. is pressing its allies to cut all oil imports from Iran by Nov. 4, a senior State Department official said Tuesday.
Teams of State and Treasury Department officials have been dispatched to Europe and Asia in recent weeks to garner support for the Trump administration's Iran strategy, telling allies that they are expected to cease oil imports from the country, the official said.
The diplomatic efforts will affect several key U.S. allies that import significant amounts of Iranian oil, including Japan, South Korea and Turkey. The Trump administration is not planning to issue waivers that would allow allies to continue importing oil from Iran, according to the State Department official."
