Russian land for Free

After finding an article on Reddit about Russia trying to increase it’s influence in Siberia by giving away free land (2.5 acres a person). Although this appears like a modern day land grab similar to what the United States did in the 1800’s 90,000 Chinese already live in the area. Are the Russians really that afraid of their Chinese neighbors annexing swathes of Siberia in a similar manner to what t is doing in the china sea?
