During his stay in Aalborg he came in contact with representatives of the Greek national team: Giannis Sgouros and Christos Iakovou and he expressed great enthusiasm for a future cooperation. However, the political situation in the People's Republic of Albania prohibited him from leaving the country. Dimas managed to cross the Greek-Albanian border at 7 February 1991, after a several hour exhaustive trip. He then stayed in Athens. He acquired Greek citizenship in 1992, and first competed under the Greek flag in the 1992 Summer Olympics, winning the gold medal in the 82.5 kg class.
