What are the pros and cons of relocating a small or midsized manufacturing firm (that makes mature products) from the united states to china?

There are usually more positive than negatives when it comes to moving manufacturing from the United States to China. It's cheaper to pay wages in China for the same type of work that someone in America would expect to be paid. Not only can you pay the workers less, you can then afford to expand and hire more people due to saving the money on American wages. Usually, you can also get products cheaper in China and cut down the cost of your product. However, with cheaper labor and materials comes cheaper quality and the quality dropping may hurt consumers willingness to buy.
