She was referencing this [1] article. And Amazon did indeed exactly what she said. They launched a side gig "Chinese Books", guided by the Chinese propaganda arm NPPA, at the behest of China exclusively in order to further their reach and business in China. That, while complying with ever more onerous requests of the Chinese government including removing reviews for certain Chinese books, granting complete control of "their" cloud services in China to Chinese government approved companies, and so forth.
It creates a reasonable argument that Amazon will do basically anything to get some of that sweet Chinese $$$, which makes their unprecedented foray into politics (at a consumer facing level), in a way that would be completely beneficial to China, look particularly bad. This still has nothing to do with using "the machinery of the state to force private enterprise" or anything like that.
