Bellamy was considering ending his Wales career after the death of his good friend and former manager Gary Speed.
But he has made himself available to boss Chris Coleman.
And team-mate Steve Morison believes the 32-year-old wants to qualify for the 2014 World Cup in Brazil to pay tribute to Speed.
He said: "Craig wants to get to the World Cup more than anybody because Gary Speed was a good friend of his. The aim was Brazil and he (Speed) went a hell of a long way to putting us on the right path."
