The company's media shy chairman, Terry Gou, repeatedly apologized for the 10 deaths this year and told reporters the firm would do everything possible to prevent more suicides. Nets were put on buildings to stop people from jumping, and about 100 mental health counselors were being trained.
"We need some time," he said. "But we are confident. We are extremely determined."
Gou said he has been having trouble sleeping at night because of the suicides, the latest one reported Tuesday when a 19-year-old man jumped from a building after working at the plant for about a month. The Foxconn head also said he dreads the sound of his own phone ringing after work hours because he's afraid it will be news of another death.
The tour with six busloads of journalists went through the palm tree-lined streets of the sprawling factory complex in the southern city of Shenzhen, near Hong Kong. The walled-in industrial park employs 300,000 workers and looks more like a small city with fast-food restaurants, bakeries, Bank of China branches and towering dormitories for workers.
Foxconn was trying to address allegations from labor groups that the workers were killing themselves because of hellish conditions in the factories, which churn out iPhones, Dell computers, Nokia mobile phones and many other big-selling electronics. Critics allege that Foxconn manages its plants with a strict military approach and workers must work too much overtime on assembly lines that move too fast.
Gou didn't take questions about such issues at a news conference, but he insisted the vast majority of workers were happy, and too much attention was being given to the troubled few.
"We want to make every worker have a happy life and work environment here," Gou said in a long, rambling speech that ended abruptly when he said he had to leave for a meeting.
Finding fresh statistics for suicides in China is difficult. The World Health Organization said that in 1999, China's suicide rate for men was 13 per 100,000 people, while the rate for women was 14.8.
Noting the figures, Dr. Hynek Pikhart, senior lecturer in epidemiology and public health at University College London, said, "The (Foxconn) rates are not probably too high or unexpectedly high."
Pikhart added, "I guess one of the reasons why these got the news they did is that maybe these are workplace suicides."
The factories making Apple products weren't part of the tour because Foxconn wanted to protect trade secrets. But the company showed off a plant with workers assembling motherboards for servers. As Gou's entourage walked through the factory, a large group of Foxconn staffers in white polo shirts fanned out and observed workers who talked to reporters.
"We're treated pretty well here," said one worker, who would only give her surname, Chen. "I think the suicides were caused by individual problems."
When asked if working conditions might have driven their colleagues to suicide, another worker, who only provided his surname, Zhang, just shrugged and said, "I don't know."
The tour included a large swimming pool near a massive cafeteria, where workers were lunching on rice, cabbage, tofu and beef with red peppers. One worker who was standing near the pool on her lunch break said she had never taken a dip.
"The pool closes too early, at 9 p.m.," said the worker, who only gave her surname, Wu. "I usually get off work at 7:30 or 8 after working overtime, and don't have time to swim."
At a counseling center in a commercial strip with eateries and a book store, a long row of young women in red shirts staffed hotlines.
Professor Stephen Palmer, director of the London Centre for Stress Management, said it was worrying all the suicides had been committed the same way - by jumping off buildings.
"Once a method becomes popular, it becomes more acceptable to other people," he said. "People who read about suicides and hear about it among people they know can be more susceptible to trying to kill themselves. ... It gives them a sort of permission to kill themselves."
He also said it was problematic that many Foxconn staffers were migrant workers. "If you're working very long hours and are away from your family, that is definitely an issue," he said.
