Moscow (Web Desk): A 14-year-old Russian model died after suffering from "utter exhaustion" during a three month modeling assignment in China.

Vlada Dzyuba collapsed into a coma after a grueling 12-hour fashion show in Shanghai, international media reported.

Sadly, she never regained consciousness and died two days later. She was found to be suffering from chronic  meningitis.

It has been claimed the teen was on a "slave labor" contract and had been too afraid to seek medical treatment.

Officially she was only allowed to work three hours a week.

A number of young Russian models are recruited to China, but Vlada's tragic case has raised concerns over working conditions for the models and how they can be exploited.

Moscow is set to demand an explanation over the conditions Vlada was living in during her time working in Asia.

The Siberian Times reported that the girl's temperature soared moments before she was set to go out on the catwalk.

Her devastated mother Oksana said: "She was calling me, saying 'Mama, I am so tired. I so much want to sleep'.

"It must have been the very beginning of the illness. And then her temperature shot up.
