In 2017, there were 24 other countries with an export volume at least 10% as large as China's: https://en.wikipedia.org/wiki/List_of_countries_by_exports

If export volume is the only factor, we'd expect to see e.g. Polish companies sending seeds at about 10% of the volume coming from Chinese companies.

One possible explanation is that EU exports frequently stay within the EU, so Polish companies would be more likely to try to get fake reviews from e.g. German customers.
