There certainly is but the downside is that often these high-value, small goods come at an extreme markup compared to anywhere else in the world.

Take, for example, Tiffany & Co. whose products are on average 30% more expensive when paying in RMB vs USD. This means that at best you will make 70% of what you are trying to extract.

It's for this reason that this is not very attractive since there are many other schemes/methods by which you can get a better extraction rate.
