I remember when Brazil did that with respect to fingerprinting. They started scanning fingerprints because US starting doing it to the Brazilian citizens when they arrived in US. Didn't follow the story after but annoying citizens of the other country by reciprocating in-like is a common strategy. Onerous visa requirements or moving from requiring to not requiring visas is also done.
