Thank you very much.
I want to thank all of our witnesses today for incredibly compelling and very timely testimony on a topic that, as you know, this committee has done previous work on. We did do a study. It was in the fall of 2018. At that time, I think it was probably some of the most disturbing testimony I had heard.
At that time, there wasn't very much in the public domain. A lot of what we heard was second-hand. There was a tremendous desire by the authorities in Xinjiang to make sure that information was not getting out internationally. Today we have first-hand testimonies, and we have studies like that of Dr. Zenz, which are documenting things in a much more concrete way.
I would be very interested in hearing the witnesses talk a little bit about what has happened since December 2018, since our study. I know that in January of 2019 when we published the summary of evidence, the very next day China did allow UN observers into the camps. My understanding is, of course, that a lot of that was very staged. Could you comment on both what has happened there and what has happened in terms of some of the international observers and what they have documented?
In particular, I will start with you, Dr. Zenz. Your testimony on the sterilization was so chilling. Perhaps you could talk about how much of that we have documented and where it is moving and how much has shifted since 2018.
