I tend to disagree with this in many ways. Chinese products are often made from subpar raw materials like steel, which can be much more brittle than steel sourced from US, Germany, and Mexico.

Professionally engineered products have their steel specified by physical attributes, not country of origin. If it meets the spec, and passes QA, it meets the spec. That being said, not every plant makes every type of steel. Higher end steels are the types of steels that western manufacturers can compete on, so it is often what they specialize in.

  Some countries declare steel to have certain properties and they do not have those properties. This is a certifiable fact.

    Manufacturers can and do test steel for compliance and will demand remediation from suppliers if it exhibits issues. I have first hand experience.
