Often quoted in this context:
I once said in passing, conjecturing that the Germans learned how to commit genocide from the Turks and this proves it.
It was a blueprint for the Holodmor before that.

The ironic/interesting thing is that the Holodomor genocide of 6-10 million Ukrainians by engineered starvation occurred in 1933, a year in which Ukraine had a bountiful harvest, which was sold to The West (Germany) in exchange for technology required to protect Socialism:
Harvest figures:
The 1931 harvest was 18.3 million tons of grain;
The 1932 harvest was 14.6 million tons of grain;
The 1933 harvest was 22.3 million tons of grain;
The Soviet regime dumped 1.7 million tons of grain on the Western markets at the height of the Holodomor.https://www.youtube.com/watch?v=afVdnbMd6gA&feature=youtu.be&t=14m14s
[Johann von Herwarth:
The government of Weimar, the democratic government, was well aware of what was going on in the Soviet Union. But the attitude of the government was, I would say, you could call it passive, and with the younger one of the Embassy we always were of the opinion then at that period that we ought not to have any commercial relations with the criminal government which allowed hundreds of thousands and even millions of people to starve. The government said we had already great unemployment in Germany, and if we stopped delivering manufactured goods to the Soviet Union, you would increase unemployment in Germany. That was the situation. ]
