What sort of restrictions? I mean, arguably tariffs are restrictions, and most countries have tariffs on imported diamonds. Would increasing the tariff percentage trigger a YES resolution? And does it have to be specific to diamonds, or would any set of general barriers that affects diamonds also count?

@AndrewHartman Good questions, increasing tariff percentage would not trigger, as that is not a new restriction. General barriers would also not trigger, except in cases where the general barriers are to luxury goods considered unethical for various reasons. I will determine this intent through reading said restrictions and media coverage on them.
