The development group, which also constructed the school, had donated more than 110 million yuan to charities and had built a school each year since 2005 in China, said Zhang.
The company worked with Chinese education charity Project Hope to find the site and get approval from the county government.
Project Hope has helped to build 15,444 primary schools and 14,000 libraries across China since 1989. The project also supported the education of 3.38 million students.
Phone calls made to China Youth Development Foundation, which runs Project Hope, remained unanswered Thursday.
However, Li Hongyi, county party chief, called the donation "selfless and respectable," according to a press release from Cohl.com
The school in Yunyang county was specially built for children of families relocated from the Three Gorges Reservoir area and most of the students came from resettled families, said Zhang.
A total of 160,000 people in Yunyang, one of China's most poverty-stricken counties, had to relocate to make way for the Three Gorges Reservoir, China's largest flood-control and hydropower project.
It can hold 22.1 billion cu m of water and is intended to curb flooding of the Yangtze River.
The reservoir led to the resettlement of more than 1 million people.
