Questions are being raised as to the legality and legitimacy of the financial returns promised on loans solicited by Zhuoda New Materials Technology from investors in China. There has been a wave of shady financial schemes in China and the web news organization Watching published its own investigations into the company. That publication was followed by the invasion of Watching's office by 60 employees of Zhuoda Group who were only driven out with the assistance of the police. The company is currently promised 20 to 30 percent return on investment in their company's business which allegedly has a contract with the Russian government to provide 3D printed housing.
