The 26-year-old France striker joined Rangers for a club-record fee from Marseille on Tuesday, 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."
Remy added: "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 today but I am keen to keep improving in the Premier League."
Remy, who has scored four goals in 17 games for France, is eligible to make his Rangers debut against West Ham on Saturday, subject to receiving international clearance.
Redknapp was thrilled with the acquisition of a player he believes has the potential to become a world-class frontman.
"I'm delighted to bring him in. He's a great buy for us," the manager told the club's official website. "I didn't think we'd get him to be honest but Tony Fernandes worked ever so hard on this. He wouldn't give up on it, and it's great that we now have him here with us.
"He's always been a player I've admired. I've watched him on so many occasions throughout the last few years. I actually spent three or four hours with him last year so he knew what I thought of him, and I think that was important.
"He's quick, can score goals and makes great runs. His movement is excellent. He's got the potential to be a really outstanding striker."
