Two Vietnamese pop stars have been co-opted into South Africa's campaign to save the rhinoceros so that they can help spread the message in East Asia, where demand for rhino horn is huge.
The two, Thu Minh and Thanh Bui, were hosted by the Wilderness Foundation, a conservation group operating from the coastal city of Port Elizabeth and which is at the forefront of saving the rhino.
The celebrities' visit was part of the foundation's demand reduction strategy, developed to assist in addressing rhino poaching by reducing demand for rhino horn in user countries, which are mostly in East Asia.
Speaking to the media on Monday evening after a tour of a game reserves just outside Port Elizabeth, Minh said: "In Vietnam we have to understand how important it is to protect the environment, wildlife and our heritage.
"The whole world is looking in horror at what we are doing to the rhino. It has to stop for the sake of the rhino and for the honour of Vietnam."
Wilderness Foundation chief executive Andrew Muir said wildlife crime was the fifth most profitable illicit trade in the world, estimated at up to US$10 billion annually. Last year, about 1,000 rhinos were killed in South Africa, compared with just 13 in 2007.
