China says nearly 1,000 real estate outlets in the nation's capital have been forced to close this year, as a slew of new government restrictions on property sales continue to cool Beijing's once red-hot property market.The official Xinhua news agency reported the slowdown Tuesday, citing a survey by the real estate firm Home Link China.The survey said Beijing has seen more than 100 real estate storefronts close in each of several consecutive months. It said more than 70 percent of the shuttered stores were owned by small and medium-sized agencies.
