You would almost think from this article that it is the Russians building military bases on shoals in the South China Sea (claimed by other countries such as Vietnam and the Philippines) and whose forces came to the aid of the North Koreans after Douglas MacArthur had his army march right up to the Yalu and had to retreat back to the 38th parallel, is now claiming sovereignty over international territory in the South China Sea, a serious threat to navigation, and has an ever-larger navy to back up the bases and threaten the neighbours, including Japan. 

So the American government might actually  recognize that they  need to work with the Russians on common problems. If not, why not?
