Even while warning about national security and human rights abuse, the U.S. government across five Republican and Democratic administrations has repeatedly allowed and even actively helped American firms to sell technology to Chinese police, government and surveillance companies, an Associated Press investigation has found. And time after time, despite bipartisan attempts, Congress has turned a blind eye to loopholes that allow China to work around its own rules, such as cloud services, third-party resellers, and holes in sanctions passed after the Tiananmen massacre. This reluctance to act reflects the tremendous wealth and power of the tech industry, which is more visible than ever under the Trump administration.
