Your best bet is likely ordering through someone who orders directly from Taiwan, or hitting up someone like blackblitz to see if they can special order something next time they do an LCT order. LCT is notoriously difficult to deal with to my knowledge, requiring a $5000 minimum order.
As for Russian manufacturers, having held an NPO in my own hands, I would recommend not bothering. They're hand made in low quantity batches, and while sturdy in some regards, are highly questionable in others. The VSK94 a friend of mine bought has low resolution, 3d printed furniture. I would suspect other Russian manufacturers to be of similar scope and quality.
