Group employee died late last night after apparently jumping from a building at the company's plant in Shenzhen, the 10th such death in the city this year, the company said.
The latest death occurred at a company dormitory around 11:20 pm, a witness told the Xinhua News Agency.
The incident came hours after Foxconn president Terry Guo pledged measures to prevent suicides after a string of such deaths at the company's Shenzhen plant.
Two other employees survived their suicide attempts earlier this year but sustained severe injuries. And another suicide was recorded at the company's plant in Hebei Province.
Earlier in the day, Guo said he regretted the tragedies.
"What I'm most concerned with is preventing the same tragedies from happening again," Guo told Xinhua.
Foxconn said it has been installing safety nets, covering 1.5 million square meters, around almost all of its dormitories and factories.
"Although this seems like a dumb measure, at least it could save a life, should someone else fall," Guo said.
The company has also divided all employees into 4,000 groups, each with 50 members, to encourage closeness within the group, he said.
Seventy psychiatrists have been hired to counsel the employees, and music is being played on assembly lines.
Of Foxconn's 800,000 employees in China, 420,000 are based in Shenzhen. They work long shifts and live inside the massive complex.
