Private equity firms Hillhouse Capital and Goldman Sachs completed a $90m investment in Arrail Dental, a Chinese private dental service provider. “Chinese people’s income keeps increasing in the last few years, which will lead to greater demand for high-quality medical services (such as dental care). In the future, the high-end dental services will have huge potential for growth. We hope that we can support Arrail to become the leading player in the Chinese dental services industry," Liu Wanlin, Goldman Sachs General Manager.
