Queens Park Rangers confirmed the move for Park Ji-Sung from Manchester United for an undisclosed fee.
The 31-year-old midfielder signed a two-year contract with the London club and is Hughes sixth summer capture, joining the likes of Ryan Nelsen, Andy Johnson, Robert Green, Samba Diakite and former United team-mate Fabio at Loftus Road.
Park leaves United after seven years, having won four English Premier League titles and one Champions League crown. He scored 27 goals in 203 appearances for the Old Trafford club.
"I am delighted to be here and be a QPR player," the South Korean told QPR's official website.
"QPR is a club with huge history and tradition, and a great ambition to achieve at the very highest level.
"Tony Fernandes and the board are striving to accomplish big things at QPR and I wanted to be part of that.
"This project was simply too good to resist, and I am excited about getting started in pre-season and going on our tour to Asia in the coming days.
"I am joining a club that is very much on an upwards curve -- a club that has a very bright future.
"The infrastructure is in place, with a new training ground and plans for a new stadium, for us to achieve in the short and long term."
"The Manager (Mark Hughes) has a proven track record at Premier League level and I am looking forward to working with him and the rest of the squad to help take this club to the next level.
Hughes said he was delighted to sign Park. "This is a real coup for QPR," Hughes said.
"We are delighted Ji is going to join us because his record speaks for itself. He has been a big player for Manchester United and played a big part in their success in recent years.
"He is hugely respected there because of what he has achieved, his application to his work and the impact he has on games.
"He was always picked for the big matches because they could rely on him, and we are going to reap all those qualities.
"I think it is fair to say Ji has been attracted not by where QPR are, but where QPR are going. We were able to show him where we feel the Club is heading and he embraced it.
"He felt this was a good option for him and after giving seven great years to United he wanted a new challenge. He sees QPR as very much a Club on the up and wants to be part of something that is going to be very special.
"Ji gets what we are trying to do. He has been part of a well-oiled machine at United and now he wants to have an impact somewhere else.
"This is a huge signing for this club."
