China Media Group has led a $14.5m series B round through its Hongxin Capital unit, bringing Gaiya's total funding to more than $25m.

China-based environmental protection technology developer Gaiya Environmental Science and Technology has raised approximately RMB100m ($14.5m) in a series B round led by media company China Media Group (CMG)’s investment vehicle, Hongxin Capital.

Founded in 2012, Gaiya Environmental provides technology and devices that are designed to remove pollution and contaminants from soil, groundwater, sediment and surface water.

The company will use the additional capital to fund the development of an artificial intelligence-powered robot and construct new research and development centres in the US and Europe.

In October 2017, the company raised $5.8m in a 2017 series A round backed by Qiminng Venture Partners, adding to the $2.7m pre-series A funding Gaiya received from Chang’an Capital in March that same year.

The company had previously closed a $2.1m in an angel round in 2015.
