Two giant pandas are now getting ready for their public debut at the National Zoo after they arrived from China early Tuesday morning.

It's been 11 months since the Washington, D.C. zoo sent its three pandas - Mei Xiang, Tian Tian and their cub Xiao Qi Ji back to China. 

The three-year old giant pandas, named Bao Li and Qing Bao, were flown from China to Dulles International Airport in suburban Virginia, with a refueling stop in Alaska. They were loaded into special FedEx trucks and arrived at the zoo just before noon.

"Our team has worked tirelessly to prepare for the pandas’ arrival, and we’re thrilled to welcome Bao Li and Qing Bao to Washington, D.C., the only place you can see giant pandas for free in the nation,” said Brandie Smith, the national zoo director who travelled to China to take part in farewell ceremonies for the bears there. "As a result of our collective efforts, today we joyfully celebrate a new chapter of our 52-year-long giant panda breeding and conservation program.”

The zoo was closed Tuesday to facilitate the arrivals.

The bears will be quarantined from the public for at least 30 days. A statement from the zoo set the date for the bears' official public debut and the reopening of the renovated panda house as Jan. 24, 2025.

Bao Li (precious vigor) and Qing Bao (green treasure) arrive in Washington as part of a new 10-year agreement with Chinese authorities. The previous deal expired last year, leading to some concern among Americans that Beijing was gradually pulling its furry friendship ambassadors from American zoos amid rising diplomatic tensions.

Breeding pairs in zoos in Memphis and San Diego had already returned to China earlier and the four pandas in the Atlanta zoo left for China last week.

Pandas have become one of the unofficial symbols of the nation’s capital, dating back to 1972 when the first pair — Ling Ling and Hsing Hsing — were sent as a gift from Chinese Premier Zhou Enlai following President Richard Nixon’s historic diplomatic visit to China. Later, a rolling series of 10-year cooperation agreements was struck.

The exact terms of the deal are still unclear; under previous 10-year agreements the Chinese government receives $1 million per year, per bear. Any cubs born in overseas zoos are typically returned to China before they reach age four.
