Russia is seeing positive developments in talks regarding a prisoner swap with Viktor Bout and Brittney Griner, Russian Deputy Foreign Affairs Minister Sergei Ryabkov said Friday, the BBC reported.

“Americans are demonstrating some outward activity. We are engaged professionally through a specially designated channel. We haven’t reached a common denominator yet. But it’s beyond doubt that Viktor Bout is one of those that are being discussed, and we certainly hope for a positive outcome,” Ryabkov said.

“We wish him the tenacity and strength to overcome the ordeal that befell him as part of the U.S. prosecution,” he added.

Griner was not mentioned specifically, but an exchange of the two has been floated before.
