The Mother was referring to a possibility that was trying to manifest since the formation of Communist China in 1949. Sri Aurobindo also spoke about the threat from Red China through Tibet. I suppose the threat was primarily till the end of Maoist regime in 1976. But She also speak about their lunar origin and the possibility of a Sino-American conflict, of which India might be a theatre. It seems that the possibility, though still there, has diminished as China has also started moving somewhat away from a rigid Maoist Communist ideology.
