It will be a difficult fight - not only because Russian troops are battle tested and the Chinese are not, but because of the weather - the Yakutia region average temperature is around 37 deg, and the schools don’t close in winter until the tempo hits minus 67 degrees.
Previous battles around the Amur region where inconclusive, with each side scoring victories and defeats.
Curious what Russia can supply in the way of troops and equipment let alone logistics
