A pair of pandas from China arrived at the Smithsonian’s National Zoo in Washington, D.C., on Tuesday, in a revival of so-called panda diplomacy after an 11-month pause that had left countless zoogoers disappointed by the absence of the lovable black-and-white bears.

After their long flight from China touched down at Dulles International Airport in Northern Virginia on Tuesday morning, the two 3-year-old giant pandas, Bao Li and Qing Bao, traveled in a police-escorted motorcade through central Washington. The bears rode in a pair of large FedEx delivery trucks bearing panda images on their sides and passed just blocks from the White House.

The transfer was announced in a statement by the China Wildlife Conservation Association, which said the pandas would visit the National Zoo under a 10-year agreement.

The National Zoo, which announced in May that the pandas would arrive by the end of the year, was closed on Tuesday to allow for a safe and orderly transfer of the bears. Zoo officials said the public would be able to view the pair after they complete a quarantine period.

The pandas have long been one of Washington’s top attractions, and excitement was already building outside the zoo on Tuesday morning ahead of their arrival. Several television camera crews along with amateur videographers staked out the zoo’s entrance. Baked by Yael, a bakery across the street from the entrance, was offering panda-themed cake pops and panda black-and-white cookies.
