Donald Trump has told White House aides to come up with possible concessions to offer as bargaining chips in his planned meeting next week with Vladimir Putin, according to two former officials familiar with the preparations.

National security council staff have been tasked with proposing “deliverables” for the first Trump-Putin encounter, including the return of two diplomatic compounds Russians were ordered to vacate by the Obama administration in response to Moscow’s interference in the 2016 election, the former officials said. It is not clear what Putin would be asked to give in return.

There is strong resistance in the NSC and state department to one-sided concessions aimed simply at improving the tone of US-Russian relations.
