Russian and South Korean scientists signed a deal on Tuesday on joint research intended to recreate a woolly mammoth, an animal which last walked the earth some 10,000 years ago.
The deal was signed by Vasily Vasiliev, vice rector of North-Eastern Federal University of the Sakha Republic, and controversial cloning pioneer Hwang Woo-Suk of South Korea's Sooam Biotech Research Foundation.
Hwang was a national hero until some of his research into creating human stem cells was found in 2006 to have been faked. But his work in creating Snuppy, the world's first cloned dog, in 2005, has been verified by experts.
Stem cell scientists are now setting their sights on the extinct woolly mammoth, after global warming thawed Siberia's permafrost and uncovered remains of the animal.
Sooam said it would launch research this year if the Russian university can ship the remains. The Beijing Genomics Institute will also take part in the project.
The South Korean foundation said it would transfer technology to the Russian university, which has already been involved in joint research with Japanese scientists to bring a mammoth back to life.
