"Qinghai Lake not only belongs to Qinghai province, but also China and the world," Wang Jianjun, Party secretary of the province, said at a news conference in Beijing on Wednesday. "It's our duty to make it more attractive and valuable."

Located in the northeast of the Qinghai-Tibet Plateau, Qinghai province is named after China's largest lake.

The province plays a significant ecological role in the country. Known as a "source of water and mountains" and sometimes nicknamed an "Asian water tower", Qinghai acts as a buffer amid global climate change and serves as an extremely significant ecological barrier for China.

In August 2016, when President Xi Jinping visited Qinghai, he said, "Qinghai's greatest value lies in ecology, its greatest responsibility lies in ecology and its greatest potential lies in ecology."

A number of large-scale land greening campaigns have been carried out over the past few years in Qinghai.
