Property conglomerate Cheung Kong, controlled by Asia's richest man, Li Ka-shing, said on Monday it will cancel sales of hotel units at a Hong Kong project after regulators ruled the deals were unauthorized investments.

Cheung Kong in February raised HK$1.4 billion ($180 million) by selling 360 hotel units at its Apex Horizons project, drawing scrutiny from the government which was concerned that Li was using legal loopholes to try to avoid a residential stamp duty introduced in October.
