 On the other hand, Lee and Sagart (1998) argued that the various layers of Chinese vocabulary are loans, and that when they are removed, a significant non-Chinese residue remains, including 15 entries from the 100-word Swadesh list of basic vocabulary.They suggest that this residue shows similarities with Proto-Loloish.James Matisoff (2001) argued that the comparison with Loloish is less persuasive when considering other Bai varieties than the Jianchuan dialect used by Lee and Sagart, and that it is safer to consider Bai as an independent branch of Sino-Tibetan, though perhaps close to the neighbouring Loloish.
