M Entertainment has announced that they have now filed a lawsuit against Tao and the production company that produced Tao's solo album. 

The agency released a statement much like the previous statements they have released against Kris and Luhan, announcing, "Our lawsuits against Tao and the album production company that aided in Tao's illegal celebrity activities have officially been registered in the Beijing Court on September 18."

The agency also said, "Tao had already been in contact with a different company in April, 2015 and started celebrity activities and proceeded with album production, leaving the team and the agency without notice. In this way, Tao used the fame he achieved from EXO to appear on advertisements and broadcasts, and on August 24, 2015, he filed a lawsuit against us at the Seoul court. Until the court makes its final decision, the contract between SM and Tao is still in effect, and Tao must uphold the contract and cannot carry out illegal celebrity activities."

The agency also stressed that the illegal activities of Kris, Luhan, and Tao are negatively affecting the vibrant cultural exchange between Korea and China, and that SM will do whatever they can to further advance the cooperation and cultural exchange between the two countries.
