The 26-year-old France striker joined Rangers for a club-record fee from Marseille on Wednesday, signing a four-and-a-half-year deal with Harry Redknapp's team after choosing the Barclays Premier League basement boys over Newcastle.
He said: "Harry played a big part in me coming here. I spoke to him and (chairman) Tony Fernandes at length and they made it clear they wanted me here. They gave me the right motivation to join QPR.
"I want to develop my game here. This season the objective is to stay up but beyond that we have greater objectives.
"After seven years in France, this is the right time for me to pursue a new challenge in the Premier League - the best league in the world.
"I am confident I can adapt to the Premier League. My main characteristics have taken me to the level I am at but I am keen to keep improving in the Premier League."
Remy, who has four goals in 17 games for France, is eligible to make his Rangers debut against West Ham on Saturday, subject to receiving international clearance.
