On Wednesday, the Laogai Museum will open on M Street in Washington, D.C. Run by expatriate Chinese dissident Harry Wu, the museum documents forced labor camps called laogai through photographs, government papers and prisoner uniforms.…The museum is backed by a noteworthy benefactor: Internet giant Yahoo Inc. Following its public apology last year for aiding in the arrest of Chinese journalist Shi Tao, Yahoo set up a human rights fund to “provide humanitarian and legal support to political dissidents who have been imprisoned for expressing their views online.” The museum is one of the fund’s first public projects.
