Milang, which has been extensively influenced by Padam (a Tani language), is alternatively classified as a divergent Tani language (Post & Blench 2011).
Koro has undergone influence from Hruso (Post & Blench 2011).
However, Milang and Koro do not belong to either the Tani or Hrusish groups of languages.
Anderson (2014),[1] who refers to Siangic as Koro-Holon instead, considers Siangic (Koro-Holon) to be a branch of Sino-Tibetan rather than an independent language family.
The following Proto-Siangic forms reconstructed by Mark Post & Roger Blench (2011:8-9) do not have lexical parallels with Proto-Tani, and are unique to the Siangic branch.
