In outright contradiction with a recent paper by Reich, Skoglund and Jakobson now propose that there is tiny bits (c. 0.67%) of Denisovan admixture among SE Asians, notably South China populations.

I must say that I really hate these highly complex papers that use ill-explained statistical modeling: they make almost impossible to make a criticism of any sort and make me suspect, right or wrong, that they could be burying, consciously or not, inconsistencies under the complex modeling.
But they could be right and I'm just to shallow to understand.
In any case, it could make some sense with a pattern I did detect in Reich 2010:
In (...) table S8.2 French, Han and Cambodians (and only them) also appear to show some admixture with Denisovans, though maybe a third or fourth of that of Melanesians.
I almost nailed it according to this paper.
It would also be consistent with the alleged 'Denisovan' introgression of HLA*A1. But this introgression was called to question, as the allele is common in Uganda however, what is inconsistent with any introgression in Eurasia and rather suggest random founder effects (or selection) from an African source.
So your take, I have no opinion - at least not a clear one.
