North Korean Ambassador to China Ji Jae-ryong took a rare tour of Chinese herbal medicine and traditional medical treatment at China's southern resort city of Sanya, according to the city government on Tuesday.

The tour took place last Friday at Chinese Medicine Hospital of Sanya, the Chinese city said in an article posted on its official website.

Reports of public activities by the North Korean envoy are incredibly rare.

A photo taken by the hospital shows Ji and his wife posing for the camera with hospital staff. Another photo shows Ji taking his blood pressure.

After receiving some treatment, Ji told hospital staff that the treatment was "very good," according to the article.

The tour was aimed at promoting the traditional Chinese medical service for foreigners, the article said. (Yonhap)
