General Secretary of the Communist Party of Viet Nam Central Committee and President To Lam attended a groundbreaking ceremony for a project on conservation, restoration and rehabilitation of Kinh Thien Palace at the World Heritage Site of Thang Long Imperial Citadel in Ha Noi on September 29.

After 30 years since 1993, when the Complex of Hue Monuments, the first World Heritage Site of Vietnam, was recognised by UNESCO, Vietnam has had 32 honoured heritages, including two natural heritages, one mixed heritage and 29 cultural heritages. They are invaluable assets contributing to enriching the cultural heritage treasure of mankind.
