Hong Kong's stock exchange needs to find ways to be more competitive as a listing venue for technology companies, without rushing into any decisions, the head of the exchange operator said on Monday.

The remarks came a day after Chinese e-commerce giant Alibaba Group Holding Ltd said it will list shares in the US.

Hong Kong Exchanges and Clearing (HKEx) respects Alibaba's decision and wishes the company well, chief executive Charles Li said in a statement.

Alibaba's move to hold a US IPO is a blow to the HKEx, which was initially the company's preferred listing venue for the deal.

"We have to consider possible changes where they might be necessary, with everything according to our due process," Li said.

"The Listing Committee's work on shareholding structures didn't start because of Alibaba and will not end now because of Alibaba."
