The Xunwu County in east China's Jiangxi province has focused on increasing its forest coverage, in an effort to protect water resources in the Dongjiang River, the main drinking water source for Hong Kong.

The Dongjiang River, a tributary of the Pearl River in the south, is originated from the Yajibo Mountain of the county.

The Xunwu County has closed its mountains for afforestation during the past ten years. The county's forest coverage has reached 78 percent, and the forest coverage for the Yajibo Mountain is 95 percent, according to the local government.

Apart from forest planting, the county has also closed down 106 rare earth mining sites, invested in projects of clean energy, soil erosion control, and water conservancy construction.
