A critically endangered species of rhino is now extinct in Vietnam, according to a report by conservation groups.
The WWF and the International Rhino Foundation said the country's last Javan rhino was probably killed by poachers, as its horn had been cut off.
Experts said the news was not a surprise, as only one sighting had been recorded in Vietnam since 2008.
Fewer than 50 individuals are now estimated to remain in the wild.
"It is painful that despite significant investment in Vietnamese rhino conservation, efforts failed to save this unique animal, " said WWF's Vietnam director Tran Thi Minh Hien.
"Vietnam has lost part of its natural heritage."
The authors of the report, Extinction of the Javan Rhino from Vietnam, said genetic analysis of dung samples collected between 2009-2010 in the Cat Tien National Park showed that they all belonged to just one individual.
Shortly after the survey was completed, conservationists found out that the rhino had been killed. They say it was likely to have been the work of poachers because it had been shot in a leg and its horn had been cut off.
Globally, there has been a sharp increase in the number of rhino poaching cases. Earlier this year, the International Union for Conservation of Nature (IUCN) published a report that said rhino populations in Africa were facing their worst poaching crisis for decades.
An assessment carried out by Traffic, the global wildlife trade monitoring network, said the surge in the illegal trade in rhino horns was being driven by demands from Asian medicinal markets.
Conservation blow
The Vietnam rhino, as well as being the last of the species on mainland Asia, was also the last known surviving member of the Rhinoceros sondaicus annamiticus subspecies - one of three recognised groups of Javan rhino populations.

Another is already extinct. R. sondaicus inermis was formerly found in north-eastern India, Bangladesh and Burma.
The remaining subspecies, R. sondaicus sondaicus, is now found on Java, Indonesia. However, since the 1930s, the animals - now estimated to number no more than 50 - have been restricted to the westernmost parts of the island.
Bibhab Kumar Talukdar, chairman of the IUCN's Asian Rhino Specialist Group, said the demise of the Javan rhino in Vietnam was "definitely a blow".
"We all must learn from this and need to ensure that the fate of the Javan rhino in [Indonesia] won't be like that of Cat Tien in near future," he told BBC News.
"Threats to rhinos for their horn is definitely a major problem. But in Indonesia, due to active work done by rhino protection units and national park authorities, no Javan rhino poaching has been recorded in Indonesia for past decade."
Dr Talukdar observed: "What is key to the success of the species is appropriate habitat management as the Javan rhinos are browser and it needs secondary growing forests."
He warned that the habitat within the national park on Java serving as the final refuge for the species was being degraded by an invasive species of palm.
"As such, control of arenga palm and habitat management for Javan rhinos in Ujung Kulon National Park is now become important for future of the species."
