Paartalu, 26, has signed a lucrative two-year deal with the Chinese side, meaning he will leave the Roar and the A-League effective immediately.
The defensive midfielder, who joined the Roar in 2010, is subject to a medical in China, where he is set to travel to this weekend.
Paartalu had earlier been banished by Brisbane coach Mike Mulvey, until he had made a decision about his future.
Paartalu started 85 straight games for the Roar since his 2010 arrival.
He will be remembered best by Roar fans for his extra-time goal in the 2011 decider against Central Coast that forced a penalty shootout which Brisbane claimed in dramatic fashion.
"The history books will always mark Erik's onfield contribution in helping secure Brisbane's first two championship trophies," Roar coach Mulvey said.
"He has been very professional in my time at the club and shown a commitment in helping the club turn things around.
"He is moving on and we now need to concentrate on the players who remain at the club."
Paartalu's departure coincided with the official arrival of Socceroo Jade North at the Roar.
