China Overseas Land & Investment Ltd.'s contracted property sales in July fell almost 24% from a year earlier to 21.49 billion yuan ($3.10 billion), the company said Thursday.

For the first seven months of the year, contracted sales at the company, one of China's largest developers, rose 0.1% to CNY193.50 billion, it said.

China Overseas Land & Investment said it acquired 11 land parcels in several Chinese cities in July. The properties have an aggregate attributable gross floor area of about 2.4 million square meters, it said.

The company's July sales decline came after it posted a 32% rise in sales a month earlier.
