A teenage Russian model has died days after collapsing from exhaustion during a 13 hour fashion show.
But, as she waited for her latest job thousands of miles from home in China, the young girl died from "utter exhaustion" and meningitis.
ESEE Model, the Chinese agency that hired Vlada, has denied the accusations that she was overworked.
Dzyuba had also contracted meningitis but she did not tell anyone because she had no medical cover.
'And then her temperature shot up.
ESEE signed a contract with Smirnoff Models, a peer agency in Saint Petersburg, earlier this year to have Dzyuba working in Shanghai for three months from August 20. Officially, she was allowed to work for only three hours a week in China.
Her agent made a decision to cancel the next day's event and sent her to the railway station on Wednesday morning to take a train back to Shanghai, Zheng said. An ambulance was called and she was taken to the hospital, but she never gained consciousness.
She had been recruited by a prominent Chinese modelling agency, it is understood.
"There is no coercive clause in this contract", he said in an interview, adding that the three-month contract didn't mention working hours. Her workload was moderate compared with other models'.
How she came to be working in China without medical insurance is not explained.
Vlada collapsed after her temperature soared while waiting for her next appearance.
She was immediately taken to the hospital but she passed away after two days.
The paper said Dzyuba's mother, Oksana, told NTV: "She was calling me, saying, "Mama, I am so exhausted".
The girl's mother, who was unable to arrange the necessary travel documents before her daughter's death, was expected to arrive in Shanghai on Tuesday or Wednesday, Zheng said.
But Zaitseva has also admitted to being unaware of the terms of Vlada's contract or whether her medical insurance was genuine, despite being in charge of the trip.
The young model's relatives fear that "a desire to profit from Vlada won against elementary care" for her.
Kremlin human rights ombudsman in Perm, Pavel Mikov, is personally investigating the girl's death.
