coming as it does

[mengta]

This finding has particular resonance, coming as it does 20 years after a severe famine in Ethiopia attracted worldwide attention through Live Aid and other events that pricked the collective conscience of richer developed countries.

what does the "coming as it does" mean?
thanks

It just links it to the time- it doesn't mean a great deal except to emphasise the fact that it really does come 20 years after the event.
