Nasdaq company with China focus says many are shut out Hong Kong Exchanges and Clearing has been urged to review its rules which ban United States-incorporated companies from listing in Hong Kong. Nasdaq-listed telecom software developer AsiaInfo Holdings said it had been considering a secondary listing in Hong Kong for some time, but had been forced to put its plans on hold because of the restrictions. 'There are many New York-listed companies like us that want to seek a listing in Hong Kong, but simply can't do it because we're a US-registered company,' AsiaInfo executive vice-president and chief financial officer Han Ying said. Under listing rules, the HKEx only accepts companies that have been incorporated in four domiciles - China, Hong Kong, Bermuda and the Cayman Islands. AsiaInfo president and chief executive Zhang Xingsheng said there was better liquidity flow in Hong Kong as retail investors were more active in trading China-focused second-tier stocks compared with their US counterparts. 'Hong Kong is our preferred market because investors here have a better understanding in companies like us that focus our business operations in China,' Mr Zhang said. An HKEx spokeswoman said the exchange only accepted companies registered under the four jurisdictions because of the similarities they shared in local company laws. Companies registered outside the four jurisdictions would not be considered for listing unless they sought special approval from the regulators. 'For companies incorporated outside these four jurisdictions, we will consider the merit of individual cases to decide to waive this requirement,' she said. Of the 844 companies listed on the main board at the end of October, only three were incorporated outside the four recognised domiciles: Canada-incorporated Manulife and UK-registered HSBC and Standard Chartered. In May 2000, at the height of the internet bubble, the HKEx allowed seven Nasdaq-listed companies - Microsoft, Intel, Dell, Applied Materials, Cisco Systems, Amgen and Starbucks - to trade in Hong Kong under a pilot scheme with the Nasdaq. However, the scheme, which is still operating, was not considered a success because of a lack of investor interest.
