There's no guarantee. It's the biggest risk in an operation.
If, let's say, a product designer has a great product and can't get it produced here in a cost-effective manner and goes to China, it's a huge risk, because what happens.... And there's a great example with Umbra, which makes household products, some great, some not so great. They own several factories in China. Whenever they produce something, the next week they see a knock-off coming out, and there's nothing they can do other than continually produce new products to stay on top of their game.
