Former Hutchison Telecommunications managing director Dennis Lui Pok-man is expected to rejoin the company as co-head of its international operations. Mr Lui, left in March last year after 13 years with Hutchison Telecom. He will share his new post with Khoo Chek-ngee, sources say. Mr Lui is expected back with the company next month. He and Mr Khoo will oversee Hutchison Telecom's international telecoms businesses - except its European third-generation mobile ventures. Previously he oversaw mobile and fixed-line operation in Hong Kong. After his departure, Hutchison Telecom split into two operations - an 81 per cent-owned joint venture with NTT DoCoMo of Japan and a joint venture with Global Crossing of the United States. Mr Lui left during last year's Internet boom to join AsiaNetCorp as chief executive, leading its merger with Korea's Littauer Technologies. Hutchison Whampoa, together with the Li Ka-shing Unit Trust, signalled their support for Mr Lui following his departure by taking a 7 per cent stake in Littauer. According to sources, Mr Lui had been in talks to rejoin Hutchison Telecom for months but did not make up his mind until recently. He was seen joining a group of Hutchison executives for a London roadshow to launch its third generation financing in Britain early this year. One source said Mr Lui would split his role with Mr Khoo, managing director of Hutchison Telecoms, overseeing non-European mobile operations. Hutchison International acquired a new mobile operation in Thailand and a Paraguay mobile licence last year, in addition to its existing operations in Australia, Israel, India and Sri Lanka. Hutchison Whampoa has expressed interest in mobile networks in Argentina and Mexico. Its annual report said it had set up a company to hold investments in mobile assets.
