Visiting a zoo with Michelle Obama

Peng and Michelle Obama will visit the Smithsonian National Zoo in Washington on Friday and check out the zoo's newest panda cub to commemorate more than four decades of scientific collaboration between the US and China concerning giant panda conservation and make a special announcement.

A pair of panda twins were born there to Mei Xiang last month, but one of the cubs died four days later.

According to the White House, the two will be accompanied by students from Washington's Yu Ying Public Charter School, which offers Chinese language study to students.
