An American patented product wants to be promoted in China. Can I apply for a patent in China?

if you want to apply for patent protection, you need to meet the conditions of patent protection, that is, inventions and utility models need to meet the conditions of novelty, creativity and practicality. The product you want to represent should belong to the products that have been sold in the United States and other countries, so it is not novel and creative, so you can't apply for a patent; Unless the related products have applied for patents abroad, and the filing date of the earlier application is within 12~24 months, they can file a patent application in China, and then go through the relevant formalities and approval.
