BEIJING, Feb 28 (Reuters) - Activity in China's services sector expanded at a slower pace in February, official data showed on Sunday.

The official non-manufacturing Purchasing Managers' Index (PMI) fell to 51.4 from 52.4 in January, data from the National Bureau of Statistics (NBS) showed. The 50-point mark separates growth from contraction on a monthly basis.

Though slower than manufacturing, China's services sector, which includes many smaller and private companies, has recovered due to strong demand.

The official January composite PMI, which includes both manufacturing and services activity, fell to 51.6 from January's 52.8. (Reporting by Colin Qian and Gabriel Crossley; Editing by Sam Holmes and Christopher Cushing)
