QPR are expected to make a number of additions this summer, and they reportedly feel that Vetokele would be a good buy.
The Belgian striker is blessed with pace and a deadly finish, making him an appealing acquisition for Chris Ramsey's side.
QPR are said to be hunting players with a point to prove, and they feel that Vetekole could fit in well with that policy.
The 23-year-old is still trying to make a name for himself in England and has made a promising start, netting 11 goals in his first season in the Championship.
If he can build on that total this year then he could be a good addition for QPR, but Charlton are understandably keen to keep hold of him.
Vetokele is the Addicks' main attacking threat and it will take a bid of around £4 million to convince them to sell.
