Factually incorrect. A country is not a race. You cannot be racist against a country, by definition, and China in particular has a very well-documented pattern of making low-quality clones of products from other countries (often using IP stolen from those countries), so the concern is well-justified.
More generally, the use of "racism" as a response to well-justified concerns about products of a country is completely irredeemable. It's logically invalid, emotionally manipulative, breaks the HN guidelines, is blatantly anti-intellectual, and is mostly used as a propaganda technique by state actors. Please keep this drivel off of platforms like HN that are designed for intellectual curiosity.
