In October 2017 Ebay seller carplatespro (aka jbeerd) from Moscow in Russia was trying to sell these replica Chinese diplomatic, US diplomatic, Equatorial Guinea and Timor Leste (East Timor) plates. He does not say how many copies of each he has.
As usual with replicas, none of the plates is quite right and the Equatorial Guinea plate is nothing like the genuine ones at all.
The big problem is going to come later when some of these plates get into the market. From a photo during a sale or trade it could be difficult to tell if the plate or plates are genuine or not.
This just makes everything difficult for everyone. Reproductions are very bad for the hobby and if you care about the future of the hobby, it is better you do not buy reproductions, especially poor quality ones like this seller makes.
