Nazrawit Abera, 27, who is an engineering graduate, was arrested on drug trafficking charges and could be sent to the hangman if found guilty.
She landed in hot water after a childhood friend asked her to deliver the bottles of shampoo which she did not know contained the Class A drug, according to local media.
Her friends and family say she is innocent and was duped into transporting the beauty products.
The childhood friend was remanded in custody by Ethiopian police but has now gone on the run and her whereabouts are unknown.
According to Ms Abera’s brother, the Ethiopian Embassy in Beijing is helping her pay for legal expenses while she awaits sentencing.
She has not been allowed any contact with family and friends since she was arrested in January.
One friend, who wished to remain anonymous, told local media:
“We are fearful, angry and do not know where to go and cry.
“We have not heard from her and we have little information of her status and her parents cry and spend sleepless nights hopping their daughter will come back.”
China operates a zero-tolerance policy on drug abuse and the death penalty is all too often handed out.
