Fan Zhiyi, who was sold by Crystal Palace to Dundee after two-and-a half-years at Selhurst Park, has been out on loan to Shanghai Shenhua since July.
Hessenthaler said: "We know that he is a good player because he played against us a couple of seasons ago.
"He has plenty of experience as his international record proves – and we have decided to have a look at him."
Zhiyi holds the record number of appearances for China with 109 caps.
