Le Diep Kieu Trang (38) will manage the development of the biggest social network in Vietnam, Facebook.

Le Diep Kieu Trang will run Facebook's Vietnamese operations from Singapore

Trang (or Christy Le) was born in a family of business tradition. Her father, Le Van Tri, is former deputy CEO of leading rubber manufacturer Casumina, while her brother, Le Tri Thong, is now vice chairman of Phu Nhuan Jewelry JSC (PNJ).

After winning a scholarship to study at Oxford University in the UK, she went on to study at the well-known Massachusetts Institute of Technology in the US.

Trang left McKinsey to help her husband establish a startup specialising in keeping track of human health and physical activities called Misfit Wearables, which then got investment from former CEO of Apple and Hong Kong billionaire Li Ka-shing.

After Misfit was acquired by Fossil Group for $260 million in 2015, Trang worked as CEO of Fossil Vietnam until earlier this March.

There is still no date announced for her new job, but the Vietnamese director will be running Facebook's Vietnam operations from Singapore.

Kenneth Bishop, managing director of Facebook in Southeast Asia, told local media that with her professional experience, Trang will be able to support companies in Vietnam.

Currently, Vietnam has around 64 million Facebook users, accounting for 3 per cent of the global user base. According to the latest survey of Nielsen, 53 million Vietnamese people were online by 2017, which will hit 59 million by 2020. The report also says that people spend over two hours per day on the social media network.
