The UK Foreign & Commonwealth Office has released its annual Strategic Export Controls report (PDF), in which it reports on military exports over the last year. It includes a few case studies, where it explains the decision-making process behind whether it allows or disallows a certain sale to be made, taking into account human rights, the risk to UK interests, risk that the equipment will be transferred to another country, and so on. This year they had a case study on Kazakhstan, and came to the conclusion that the sale would be OK:
