HONG KONG, May 11 (Reuters) - Chinese real estate developer Beijing Capital Land (2868.HK) said revenues from flat sales in the first four months rose 200 percent from a year ago, as the outlook for the mainland property market improved.

The company sold about 2.54 billion yuan ($372.5 million) ($73.07 million) worth of flats in the first four months, with the contracted sales area surging 270 percent from a year ago to 281,000 square metres, according to a newsletter from the developer.

The developer said sales in the January-through-April period were derived from projects that are scheduled to be completed this year in major cities in Beijing, Tianjin, Chengdu and Shenyang.

Growth momentum accelerated in April with contracted sales amounting to 1.13 billion yuan, up 24 percent from March, it added.

The company had said earlier this year it had set an ambitious sales target of 6 billion yuan in 2009, counting on a boost from government measures aimed at stabilizing the property market.

The company shares, which rose nearly 27 percent in the first four months of this year, fell 3.06 percent to HK$1.90 in mid-morning trade on Monday while the broader market .HSI gained 0.46 percent. (US$1=HK$7.8=6.819 yuan) (Reporting by Donny Kwok; editing by Ken Wills)
