Looks like that goodwill meeting with Vladimir Putin worked ... because Roy Jones Jr. tells TMZ Sports he just booked his first fight in Mother Russia.
RJJ just reached out and told us he'll be fighting Welsh bigman Enzo Maccarinelli on November 28th.
Enzo is a former WBO cruiserweight champ ... who's fighting to regain his belt on October 10th.
If Enzo wins that belt, the Jones fight would be a title bout.
This is big news because Jones just flew out to Moscow for a face-to-face with Putin -- and asked for Russian citizenship so he could do business in Vlad's country.
Jones has said his ultimate goal is to help repair U.S./Russia relations.
