Chow Tai Fook Group, the privately held enterprise of Hong Kong New World Development, has rolled out its luxury apartment project in Beijing. The project, named Shadow Creek, consists of 89 luxury villas in the first phase, with a selling price expected to be around 6,000 US dollars per square meter.   "Jewellery and luxury properties are closely bonded since both represent the lifestyle of wealthy elites, and I'm confident about the market potential thanks to the booming demand on the mainland," said Cheng Yu-tung, founder and group Chairman.     Other high-end residential properties in Beijing developed by flagship real estate developer New World China Land focus on the key market segments of the high-end market.   Dr Cheng said, "New World China Land, the mainland property arm of Hong Kong-listed New World Development will roll out more property projects over a long term, showing its commitment to the investment in the mainland."
