China is celebrating the birth of twin pandas on Monday after their mother was artificially inseminated earlier in the year.

With their eyes still tightly shut and their legs struggling to support their weight, the little cubs had their first public display from the incubator on Tuesday.

• China’s wild panda population up 17 per cent

While the pair only weighed 118g and 70g at birth, they will grow to be more than 75kg by the time they fully mature.

Seven-year-old panda Kelin gave birth at Chengdu Research Base of Giant Panda Breeding after being artificially inseminated in January.

Chief administrator Wu Kongju said the giant pandas were doing well based on their milk consumption and had normal body temperatures.

The sisters are a welcome addition, with fewer than 2000 pandas left in the wild.
