Boko Haram's Motives, Only a Partial Story

The news of 29 people murdered in Nigeria over the weekend is simply tragic.  The likely culprit is a group called Boko Haram which Bloomberg tells us means:

“western education is a sin” in the Hausa language

Four paragraphs down in the very same article the authors state:

suspected Boko Haram militants killed a soldier and kidnapped 10 workers from China in a May 16 attack on a camp run by a Chinese engineering company in Cameroon. 

If Boko Haram's enemy is western education why are they targeting people from China?

Are we perhaps not hearing the full spectrum of the groups motives?
