"Yuen Meng was born here, even though he is from elsewhere," Brigitte Macron said. "He is the energetic and vigorous fruit of Franco-Chinese friendship."

Yuan Meng was born to mother Yuan Yuan on August 4, along with a twin which died shortly after birth.
The cub now weighs 7.9 kilograms, compared to just 142.4 grams at birth, according to the zoo.
The pandas have been in France since 2012 as part of a research and breeding programme in cooperation with the Chengdu panda centre in China.
China, which retains ownership of all giant pandas loaned to zoos abroad, sent two specialist panda carers to look after the new arrival.
