Fourteen panda cubs made their debut during a news conference at the Chengdu Research Base of Giant Panda Breeding in Sichuan Province, China.
Twenty baby pandas were born there this year, of which 17 survived.
They join 128 giant pandas at the facility.
An estimated 1,800 giant pandas still live in their natural habitat and fewer than 300 in zoos and preserves. They remain on the critically-endangered list.
Pandas struggle to procreate because of low sex drive and fertility issues.
Pandas have been shown videos of other pandas mating and even given Viagra, but many successful births have been the result of artificial insemination.
