The People’s Committee of central Ha Tinh province held a ceremony on October 16 to receive a certificate recognising "Hoang Hoa su trinh do” (The Envoy’s Journey to China ) as one of documentary heritage in Asia and the Pacific under UNESCO’s Memory of the World Programme.

"Hoang Hoa su trinh do” (literally translated as maps and itinerary of the envoy’s journey to China) belongs to the Nguyen Huy family in Trường Lưu village (now Truong Loc commune, Can Loc district).

With writings, drawings and maps, the book recorded the diplomatic relationship between Vietnam and China in the 18th century through journeys of Vietnamese envoys. It was compiled and edited by Nguyen Huy Oanh (1713-1789) based on documents of previous envoys and historical records as well as notes from his own journey in 1766-1767, during which he worked as the main envoy of the Vietnamese delegation.

The Memory of the World Programme is an international programme aimed at safeguarding, preserving and facilitating access to and the use of documentary heritage. UNESCO launched the programme in 1992. It includes the inscription of significant documentary heritage on national, regional and international registers.-VNA
