Hong Kong, Nov 16 (Reuters) - China and Hong Kong stocks fell on Thursday after Beijing's latest measures to revive the struggling property sector failed to boost investors' mood.

** At the midday break, the Shanghai Composite index was down 0.32% at 3,428.37 points. China's blue-chip CSI300 index was down 0.31%. Hong Kong's benchmark Hang Seng Index was down 0.88% at 19,649.91.

** China's latest effort to shore up the crisis-hit property sector via tax incentives on home and land transactions failed to improve stock prices in the sector.

** The CSI real estate index was down 0.52%, and the Hang Seng Mainland property Index slid 2.25%. Developer Longfor was among the top losers in Hong Kong, falling 5% to its lowest since late September.

** Bucking the trend, Chinese technology company Tencent climbed as much as 2.8% after posting an 8% rise in September-quarter revenue.
