China on Tuesday issued a guideline that outlines the country's biodiversity protection goals.

According to the goals, protected natural areas, mainly national parks, will account for 18 percent of China's land area by 2025, when China's forest coverage rate and comprehensive grassland coverage will increase to 24.1 percent and 57 percent, respectively.

China will place 55 percent of its wetlands, 35 percent of its natural coastlines, and 77 percent of its wildlife species under key state protection. Approximately 92 percent of China's terrestrial ecosystem types will be effectively protected.
