Even having product cast or manufactured in China to save on production costs is to a point self defeating. Any company you contract with or any partner you take up with to set up production in China is attached at the hip to the CCP. They have little to no respect for intellectual property rights, so will set up another company in a nearby city to produce a knockoff, copy or reverse engineered product to undersell you. You spend the money to design and develop a product which is expensive. Knocking out copies is very inexpensive, so they can underselk your product by a large amount and still made a substantial profit.
