This is interesting...First off.. it looks like Chinese policies really are putting pressure on companies that produce TiO2 to clean up their environmental act. (I had to use the cached version). The recent pollution events more continuous exposure, making the industry of titanium dioxide environmental policy tightening is expected to become more intense.
Analysts said that the domestic titanium dioxide enterprises are facing the dual pressures of market and environment, the survival is not easy. Titanium dioxide industry to carry out environmental protection technology reform, industrial upgrading is imminent.

"Each of these individuals allegedly sold information containing DuPont TiO2 trade secrets to the Pangang Group companies for the purpose of helping those companies develop large-scale chloride route TiO2 production capability in the PRC, including a planned 100,000 ton TiO2 factory at Chongqing, PRC."

"However, 2 years later, in 2012, the very promising Pangang Group had stuck in a corporate espionage: it was accused and charged by DuPont for stealing the commercial secrets of the manufacturing technique for producing the chloride-grade TiO2.
Though Pangang Group had kept silence on the accusation, its 100,000 t/y of the chloride-grade TiO2 project ended up with nothing."
Three.... It looks like they are starting up this project again. "Pangang Group Vanadium Titanium & Resources Co., Ltd. (Pangang Vanadium Titanium) announced that it would invest about USD 17.2 million on the new project of Titanium Dioxide (TiO2) produced by chloride process. The project is expected to be completed and put into trial operation at the end of December 2016."
