The 28-year old French striker has penned a three-year deal with Dalian after four-and-a-half years in Paris and his exit was felt by PSG midfielder Nene.
"It will be a loss," he told l'equipe.fr.
"He has brought a lot to the club since his arrival, he scored and set up a lot of goals. He is a very talented player."
Hoarau kicked off his professional career with Le Havre in 2004, where he had a loan spell with Gueugnon, prior to his 2008 shift to Parc des Princes where he scored 45 goals.
