Regional telecommunications operators are looking forward to taking away market share from the Asian unit of WorldCom, which filed for Chapter 11 bankruptcy in the United States at the weekend. They said concerns about a possible collapse of WorldCom Asia Pacific, which was not among the bankruptcy filings, would see some of its customers switch to other long-established operators in the region. 'Put yourself into the customer's position, what would you be looking for now?' said Alex Arena, chief financial officer of Pacific Century CyberWorks. 'Not a new start up, but you'd be looking for established incumbents that had been, and will be, here for a long time.' Mr Arena said Reach, a joint venture between CyberWorks and Telstra, expected to pick up 'quite a lot of business' from WorldCom. WorldCom recorded US$1 billion in sales last year in the Asia Pacific region, mainly from multinational corporates. AT&T Asia Pacific, one of WorldCom's closest competitors in the region, also said it was looking for growth opportunities. 'We have found some flight to quality when competitors have been in difficulty as customers look for partners that offer stability, reliability and long-term support. Our business in Asia continues to grow while others are cutting back,' said Greg Brutus, regional public relations director with AT&T. WorldCom does not operate a network in Asia, and is one of the largest consumers of bandwidth in the region by swapping capacity with telecoms providers. Tony Cheung Tung-lan, vice-president of Wharf New T&T, said the company provided a data line service to WorldCom, which had a perfect payment record. WorldCom filed for bankruptcy on Sunday in what was considered to be the largest bankruptcy in US corporate history. The No 2 long distance operator in the US has debt of more than US$41 billion.
