China's official archives relating to Tibet in the Yuan Dynasty (1271-1368) and documents showing the ancient financial and messaging service operated between overseas Chinese and relatives back home have won a major UNESCO recognition.

A meeting of the International Advisory Committee of the "Memory of the World Register" has decided to include these two sets of documents on the register, a statement from the State Archives Administration said on Friday.

The meeting was held from June 18 to 21 in Gwangju Metropolitan City of the Republic of Korea.

The Memory of the World Register lists documentary heritage recognized as globally significant and having outstanding universal value.
