The head of State, who is attending the High-Level Segment of the 78th regular session of the United Nations General Assembly, congratulated Rosillo on his X account, formerly Twitter, on Saturday.
After a long period away from the rink, the Santiago de Cuba-born Greco-Roman wrestler has achieved the most important result of his career, Díaz-Canel noted.
Rosillo (97 kilograms) defeated Armenia’s Artur Aleksanyan, 2016 Olympic champion, in the gold-medal fight on Saturday.
The bronze medals in this category went to Artur Omarov (Czech Republic) and Mohammad Hadi Saravi (Iran).
Rosillo’s was Cuba’s first title in the contest.
