A very new sublineage, and it is widely distributed - Heilongjiang is in northeastern China while Sichuan in southwestern China.
Nowadays XBB.1.9.1 is the dominant sublineage in China, and we may keep monitoring.

16seqs now (Sichuan Province: 6 seqs)

clearly recent one with a significative early spread, known residue mutated in fast lineages, localized in a country with pandemic peculiar dynamics so i think it is better monitoring it officially in the pango page.

22 seqs now (6 more seqs from Hubei Province). I’ll move it to main page if reaches 50 or an abroad sample is detected

[HynnSpylor]

It expands strikingly in China and reaches 57. I’ll move it to main page.
