ATLANTA -- It appears that a pair of panda twins born in Atlanta are having trouble getting used to China.

According to Chinese news outlets, Mei Lun and Mei Huan like American biscuits more than Chinese food.

"The naughty twins refused to eat traditional Chinese food like steamed bread of corn," Chinese media service Xinhuanet reports.

They're also only responding to English commands.

The female pandas were born at Zoo Atlanta in 2013 - the first giant panda twins to be born on U.S. soil and survive.

But they were sent to their new home in China in early November under rules of "panda diplomacy".

The twins, who are the fourth and fifth Atlanta-born pandas to travel to China, were accompanied by two Zoo Atlanta staff and a considerable amount of panda-particular luggage, including around 375 pounds of bamboo, 8 gallons of water, and 25 pounds of favorite treats, including sugarcane, bananas and giant panda biscuits.

Now staff in China are working to slowly wean the two off of American food and onto more native panda cuisine, Communist Party-run People's Daily reports.
