French President Emmanuel Macron has pitched US President Donald Trump on a plan to end the standoff over the Iran nuclear deal—by allowing Iran to sell oil for a limited period of time, in exchange for returning to talks and to compliance with the agreement, Bloomberg reported.

The proposal was made after Macron and Trump sat down to a lunch at the Group of Seven Summit in Biarritz, France.

A senior US official, however, termed the plan a non-starter.

The French side did not comment on Trump’s response to this proposal. But should he accept the proposal, it would be a comprehensive change in his Middle East policy.
