Just having opened in the summer of 2008, the embassy of China is a bold statement by the emerging superpower on the global stage. It was designed by two sons of the famous Chinese-American architect I.M. Pei and his influence can be seen in the geometrical similarity to his National Gallery on the Mall. The 250,000 square foot building is one of the biggest foreign embassies in Washington, taking up almost an entire block just off Connecticut Avenue. The Chinese government stirred some controversy when they imported hundreds of their own workers to construct the building, rather than employ local labor. Security concerns were noted, but American labor leaders point out that hundreds of Chinese workers were employed by the construction of the sprawling $464 million US embassy in Beijing.
