"Several accounts belong to the same parent firms, as it’s normal for big sellers, those with more than a million dollars in annual sales, to operate multiple brands on Amazon to optimize sales…In total, the suspended accounts are claimed to contribute over a billion dollars in gross merchandise value (GMV) to Amazon."
Amazon references “long-standing policies to protect the integrity of our store, including product authenticity, genuine reviews, and products meeting the expectations of our customers.” when asked for comment.
So, not specifically because they are from China.
Thanks for the clickbait title.
