Vlada Dzyuba, 14, from the industrial city of Perm in Russian Federation, missed school to work on catwalks on a "three month contract" to realise her dream of becoming a supermodel.
Vlada's mother was unable to reach her daughter before she died as her last-minute via was not cleared in time.
Moscow is set to demand an explanation over the conditions Vlada was living in during her time working in Asia.
She was found to be suffering from chronic meningitis. "I want so badly to sleep".
She was supposed to only have been working a maximum of three hours per week.
The head of the Perm modelling agency behind her trip, Elvira Zaitseva, said: 'No-one expected it to lead to such consequences.
Officially she was allowed to work three hours a week in China, a law which mirrors that in Russian Federation. The ambulance arrived quickly and took her to the nearest hospital.
There is speculation that Vlada did not go to the hospital sooner because she had no health insurance in China.More news: 'Batshuayi is ready to start' - Conte backs Chelsea striker

She had been prominent at this month's prestigious Shanghai Fashion Week. Under Chinese law, the teenager was only allowed to work three hours a week. Her workload was moderate compared with other models'.
Sadly, the young model Dzyuba failed in the battle of life and said goodbye to the world after being in a coma for 2 days as she failed to regain the consciousness.
Her distraught mother Oksana wept: 'She was calling me, saying "Mama, I am so exhausted".
It is also not clear who is to blame for her not having medical insurance.
"Leaving aside any blame, her tragic story is likely to hold lessons for those - anywhere - who deploy teenage girls as models, often enticing them with starry-eyed hopes of fame and fortune in the future, a goal reached by only a handful", the Siberian Times concludes.
The young model's relatives fear that "a desire to profit from Vlada won against elementary care" for her.
Police are now investigating what caused her death.
"We feel sorry that we lost an angel", ESEE Model Management in Shanghai said in a statement on Weibo, China's equivalent of Twitter, pointing out that Shanghai Fashion Week ended on October 18, but she fell ill six days later.
