A spokesperson for the American Chamber of Commerce in Beijing also told CNBC that U.S. companies are staying in China, but they are looking to diversify where their components come from or products are assembled.

Nearly two-thirds of respondents to a survey by the chamber said they are not relocating or considering such a move. Only 13 out of more than 430 companies surveyed are considering leaving China — but rather than choosing the U.S., Southeast Asia is the top destination.
