Hong Kong will continue to serve as "China's international exchange", and will widen its listing sources to maintain its position as Asia's largest listed bourse.

That is the message from Paul Chow, chief executive of Hong Kong Exchanges and Clearing (HKEx), the operator of the world's seventh-largest bourse.

"Our three-year strategic plan for 2007-09 involves the major themes of reinforcing our position vis--vis the mainland," Chow told China Daily.

His remarks appear to address concerns that Shanghai will steal the luster of Hong Kong after an increasing number of mainland companies chose to list in the yuan-denominated A-share market instead of in Hong Kong.

The Shanghai market recently peaked after a five-year lull, having lured Hong Kong-listed mainland giants like Bank of Communications, China Mobile and China Construction Bank back to the home market.

Chow, however, sees more opportunities than challenges ahead. He said cooperation between Shanghai and Hong Kong, domestically and internationally focused respectively, would be beneficial to the mainland's robust economy.

With a bullish Shanghai market, the two bourses could both benefit from hosting more dual listings.

Chow said the Industrial and Commercial Bank of China's (ICBC) simultaneous dual listing set a good precedent, and that Hong Kong and the mainland had set up a working group to review arrangements for simultaneous listings.

"We are convinced there are ample listing resources and room for us all," he said. And Hong Kong's attraction as China's international market still helps it stand out.

Hong Kong boasts every element that an international exchange requires good market scale, rich liquidity and global exposure.

At the same time, it is attractive to the mainland for its geographical proximity and relatively low language and cultural barriers that other overseas markets do not have.

That's why the number of mainland firms listing in Hong Kong has risen steadily over the years and a lot more have expressed interest in listing in Hong Kong, he said.

More than 300 mainland firms are currently listed in Hong Kong, accounting for nearly 40 percent of the market capitalization. Last year, the ICBC and Bank of China's $30 billion initial public offerings (IPOs) helped the city to surpass New York as the world's second-largest IPO market, only after London, after it saw record $43.8 billion IPOs.
