How do Chinese exports move money out of China???On the contrary actually. Due to their real estate bubble collapsing they are trying to prevent their RMB from free falling right now.
Why do you think they are buying so much gold? Why do you think there is a withdraw limit on their own people inside China? Why do you think the black market smuggling rate to convert RMB in China to USD in a foreign country cost 20% service fee to the launderers?
Many of their exports are really just to break even and move money out of China. Unfair sure, but it is more of a money collapse prevention issue instead of intentionally trying to tank their own currency.
