European (SXXP) stocks declined, following nine months of gains for the Stoxx Europe 600 Index, as measures of manufacturing in the U.K. and China dropped, while a report showed euro-area unemployment has climbed to a record.

The Stoxx 600 retreated 0.3 percent to 289.02 at the close in London, paring an earlier slide of as much as 1.1 percent.

China’s manufacturing growth unexpectedly slowed last month. The country’s official purchasing managers’ index slipped to 50.1 in February from 50.4 in January, the National Bureau of Statistics and China Federation of Logistics and Purchasing said today in Beijing. The reading compared with the 50.5 median estimate in a Bloomberg News survey of 31 economists. A number above 50 means that activity increased.

European stocks pared their decline after the Institute for Supply Management’s U.S. factory index increased to 54.2 last month from 53.1 a month earlier. Economists had projected the gauge would decline to 52.5, according to the median forecast.
