Hong Kong Exchanges and Clearing hopes to have the regulatory framework in place to allow business trust listings within the next few months to help level the playing field with Singapore Exchange Ltd, which already allows such listings. \"The remaining issues are highly technical, but HKEx hopes they can be resolved soon and that a framework will be ready within the next few months,\" a spokesman for Hong Kong Exchange said in an e-mail. In March, tycoon Li Ka-Shing listed the ports business of Hutchison Whampoa as a business trust in Singapore, rather than in his home city of Hong Kong. from / Gulf News
