On August 15, 2014, an Option and Joint Venture Agreement was signed between a subsidiary of CGCOC Group Co., Ltd and an African company in which CGCOC Group would invest in a local gold mine exploration project. It is a typical case in which a Chinese enterprise, whist following internationally established practice, provides venture capital for mine exploration. 

A team led by Beijing-based senior partner Yang Guisheng worked jointly with local lawyers in advising CGCOC Group on the investment. Their work included transaction structure design, due diligence, drafting, reviewing and revising legal documents and participating in negotiations. Yang was assisted by partner Zhang Ting, associates Zhu Biyun, Wang Yixuan and Yang Haoran .

CGCOC Group is a mix-ownership business founded jointly by natural persons. It is engaged in large-scale petrochemical engineering, mine prospecting, engineering and construction. The group offers consulting, planning and construction services and conducts industrial investments in infrastructure such as water supply, road and bridge, airport, housing, undertakes property development for industrial, rural and urban use, energy and mineral resources development, equipment and financial lease as well as comprehensive high-end consulting services.
