Barca captain Iniesta, 33, said in April he would leave the club he joined as a 12-year-old in the summer, with media reports suggesting he would be moving to Chongqing.
In a statement on social network Weibo on Friday, the Chinese side's president Jiang Lizhang said they are working with Iniesta in areas including marketing and youth education, but there is no deal for him to play.
Chongqing said they would adhere to rational investment and follow rules set by the government-controlled Chinese Football Association, which includes a salary cap.
Spanish reports had indicated Iniesta was close to agreeing a three-year deal with Chongqing, worth 81 million euros ($129 million).
