To get the discussion back on track, there are three assertions in the OP.
A- China is trying to replace America as the dominant military force in the region
B- Such a replacement is unacceptable to India, and
C- India should ally itself with the US to prevent that change
Assuming that A) is a given, the question arises why B) should be true. What does India care who is the local policeman? Unless India has ambitions of its own to fill that role.
Note that the other countries in the region -- Japan, South Korea, Vietnam, etc. -- are not particularly bothered about each other. They only care about their particular concerns vis-a-vis China. Only India seems to be volunteering itself for the role of deputy sheriff (for the US) in the South China seas.
The article, then, is an implicit acknowledgement that India has hegemonic designs within Asia, and that such aims can be achieved by convincing the US to 'outsource' its Asian hegemony to India.
