German Chancellor Martz said he may meet with Putin in December:
The President of the United States must be able to hold a reasonable dialogue. And I would like to add - as I believe some of you have already asked this question - that one day it should happen to Putin. Perhaps such a meeting will take place in December.
It is not included. The G20 summit will be held in Miami on December 13-14. The host country has the right to invite additional heads of state and government. As far as is known, Trump invited Putin.
It is not yet known if he will arrive. He has not yet given his consent. But if Putin is present, I do not shy away from the opportunity to negotiate with him.
