Ren founded Huawei in 1987 with a few thousand dollars in the southern city of Shenzhen, near Hong Kong. He is now 75.
In a rare interview with foreign media earlier this year, Ren said he only saw his children for one month a year while in the military.
After founding Huawei he worked 16-hour days, with barely any time for his family.
“Especially my youngest daughter, I was even more distant from her. So all I can say is, as a father, I feel I owe them,” he said, according to a transcript of the interview.
Ren’s military background has fuelled concerns that Huawei might have links with Chinese authorities, which the company has consistently denied.
