China's cultural relic watchdog will accelerate drafting of a plan to protect the Great Wall, and implement more rigid supervision of the UNESCO World Heritage site.

"A nation-level supervision platform to oversee and manage protection of the Great Wall is being constructed," Liu Yuzhu, director of the State Administration of Cultural Heritage, said on Wednesday.

"A detailed plan to coordinate efforts in different provinces nationwide will be released by the end of next year," Liu said, adding that drones will be used to enhance daily supervision of the Great Wall.
