The 33-year-old Cardiff striker has missed the first four matches of the Dragons' World Cup qualifying campaign, but he has been included in Chris Coleman's group for next week's Liberty Stadium encounter.
Bellamy has not played for his country since the 2-0 defeat to Bosnia-Herzegovina in August of last year, and his absence fuelled speculation he was set to step down from international football after 70 caps and 19 goals.
Chris Coleman: "I never thought Craig would knock it on the head.
"As you get older, physically it is harder to keep playing international football. Craig had a few problems last year and it was difficult for him, but he has that spark in his eye for football.
"He has already played 70 times for Wales, so he has paid his dues and turned up for friendlies and end-of-season games; not everyone does that.
"But he has fallen in love with football again, Cardiff are getting the rewards of that and it will be nice to have him back in the squad.
"I had a really good chat with him seven to 10 days ago. Cardiff are doing well and Craig's fitness is good.
"He is playing down the middle, which I think is his favourite position, so I think it is all positive and be nice to have him back.
"We will take it game by game, he has had his injury problems and is not getting any younger, but has a lot to offer provided he is fit physically and mentally."
