The Dutch attacker will leave the Bundesliga club after seven seasons but is looking to stay close to home rather than moving to a team in Asia.
Klaas-Jan Huntelaar has confirmed he will leave Schalke at the end of the season, but ruled out a move to "some club in the desert, China or Turkey".
Huntelaar has cut a frustrated figure at the Veltins-Arena this season with only five starts in the league as he has slipped down the pecking order.
The 33-year-old's lack of action has led to him seeking a move away from the Bundesliga club, with reports linking him to former club Ajax.
