China has put on display the latest twin pandas born through artificial insemination as part of efforts to boost the numbers of its unofficial national mascot.

Still mostly hairless and with their eyes yet to open, the sisters were met by adoring fans at a breeding centre in the south-western city of Chengdu.

Their mother, seven-year old Kelin, gave birth to the twins early on Monday.

Wu Kongju, chief administrator at the Chengdu Research Base of Giant Panda Breeding, said the twins were in good condition based on their milk consumption and normal body temperature.

The cubs were born more than four months after the mother was artificially inseminated in January.

Figures released this year show 1,864 pandas live in the wild.
