The Chinese are successfully breeding Siberian Tigers:
Eighty-four Siberian tigers, among the world’s rarest animals, have been born since March 2007 at the Hengdaohezi Feline Breeding Center in the suburbs of Harbin, capital of Heilongjiang province, an official said Sunday, June 17, 2007. Fewer than 400 Siberian tigers — also known as Amur, Manchurian or Ussuri tiger — are believed to survive in the wild, about 20 of them in China and the rest in Russia.
