The 24-year-old swapped west London for Sevilla in the summer having failed to make his mark at Stamford Bridge and spent loan spells with six different clubs.
Sevilla reportedly had to pay 3.5million euros ($5.5M) compensation for the out-of-contract Kakuta - a fee they are reported to have nearly doubled by selling the Frenchman onto China.
Former Chelsea team-mate Ramires, Liverpool target Alex Teixeira and Colombia striker Jackson Martinez have all made big-money moves to the Chinese Super League in recent weeks.
Kakuta now joins former QPR midfielder - and Sevilla team-mate - Stephane Mbia at Hebei China Fortune, where ex-Arsenal forward Gervinho is now plying his trade.
Kakuta moved to Chelsea as a teenager in 2007 and became a prominent player for the Blues' youth team, graduating to the senior squad after two years in west London.
However, in September 2009, FIFA banned the player for four months and placed Chelsea under a transfer embargo due an alleged breach of contract with former club Lens.
The transfer ban and suspension were successfully appealed against, but Kakuta would struggle for first-team action and went on loan to Fulham, Bolton, Dijon, Vitesse Arnhem, Lazio then Rayo Vallecano.
