Many of his finest accomplishments came for Team Sweden in international play, as he helped his country to several medal finishes at both the Winter Olympics and World Championships during the 1980s.

Over the next few seasons, he emerged as one of the club's top two-way players, culminating in his selection to play for Sweden at the 1980 Winter Olympics in Lake Placid.

His NHL options at an end, Molin returned to Modo for 1984–85, and turned in the highest-scoring season of his Swedish league career, posting 57 points in just 32 games.

He continued his strong play with the club for the next few seasons and experienced another career highlight when he helped Sweden to a Gold Medal performance at the 1987 World Championships.

Now well into his 30s, Molin left Modo in 1988 and dropped down to the Swedish 2nd division with Örebro IK, where he spent the final 3 seasons of his career before retiring in 1991.
