Mayor Vincent Gray Reaffirms D.C. Sister-City Status With Beijing, China

WASHINGTON -- When you cross the city limits of plenty of locales around the nation, you'll see signs announcing sister-city relationships with places around the world.

The District of Columbia is no different. But most of its sister cities are fellow world capitals. On Tuesday, D.C. Mayor Vincent Gray, who is currently on a trade mission to China, reaffirmed the sister-city relationship with Beijing, first inked in 1984.

D.C.'s Chinatown Friendship Gate on H Street NW was a result of that initial sister-city agreement.

"I am thrilled that our relationship with the city of Beijing will be extended and expanded to focus not only on educational and cultural exchanges, but also on concrete actions that will result in economic development for the residents of both Beijing and the District," Gray said in a statement released by his office. "By emphasizing partnerships in the arenas of real-estate development, tourism, investment, sustainability and technology, we are promoting global trade at the local level."
