"The stamps are to honour as well as to preserve the cultural and natural values of Trang An complex." said Information and Communication Minister Nguyen Bac Son.

"The ministry issues the stamps to introduce Vietnam's scenery and other masterpieces to the world and to attract visitors," Son said.

Trang An complex covers 12,000ha and features a well-developed river and stream system left after inundation by the sea many times in the past. It features mainly primary tropical forest with caves and underground streams. Trang An is also a complex of limestone karst peaks, most of which tower 200m.

UNESCO put the complex on the World Heritage List on June 23 last year, citing its cultural value, aesthetic beauty, and its geological and geomorphological significance.
