Asian stock markets lost ground on Monday, with investors little moved by the G20's weekend commitment to boost global growth by $2 trillion over five years. In Tokyo the benchmark Nikkei-225 index fell 0.19 percent, or 27.99 points, to close at 14,837.68. "Players tried to lock in some profit... and they are waiting for US economic indicators, which appear unpredictable due to the impact of the recent winter storm," said Toshikazu Horiuchi, a broker at IwaiCosmo Securities. "But today's decline was limited, indicating that market sentiment is not so bad at all," Horiuchi added. Sony rose 0.50 percent to 1,775 yen after the company released PlayStation 4 consoles in Japan during the weekend. Toyota fell 0.96 percent to 5,924 yen, while its rival Nissan edged down 0.10 percent to 918 yen. Hong Kong shares fell 0.80 percent, or 179.68 points, to end at 22,388.56. China Overseas Land and Investment dropped 3.6 percent to HK$20.25, Hang Lung Properties slid 2.8 percent to HK$21.10 while Belle International Holdings rose 5.9 percent to HK$9.32 after the footwear maker reported stronger profit margins in full-year 2013 results than analysts expected. On the Chinese mainland, shares extended losses on worries about possible tightening of credit to the property sector. Shanghai dropped 1.75 percent, or 37.00 points, to close at 2,076.69. The Shenzhen Composite Index, which tracks stocks on China's second exchange, narrowed earlier losses to close down 0.07 percent, or 0.82 points, at 1,134.19. China's domestic banks have recently tightened lending to the real estate sector, state media said last week, although the four biggest state banks on Monday denied any such moves. Official data released Monday also showed fewer cities, 62 out of 70 tracked, recorded month-on-month increases in new home prices in January, down from 65 in December. Analysts said fears were overblown. "The (property) market doesn't have any structural risks and the government wouldn't clamp down too tightly on an area so important for China's economy," United Securities analyst Pei Xiaoyan told Dow Jones Newswires. Seoul lost 0.45 percent, or 8.78 points, to end at 1,949.05 and Sydney closed a marginal 0.03 percent, or 1.5 points, higher at 5,440.2.

Oil prices rebounded in Asia owing to strong US demand driven by prolonged sub-zero temperatures across much of the country and geopolitical worries.
