European stocks retreated, following their biggest weekly gain in a month, as China’s economy grew at a slower pace than estimated and a gauge of manufacturing in the New York area missed forecasts.

In China, gross domestic product rose 7.7 percent in the first quarter, the National Bureau of Statistics said in Beijing.

The country’s industrial production increased in March at a slower rate than economists had estimated, while retail-sales growth matched forecasts.

In the U.S., the Federal Reserve Bank of New York’s general economic index slowed to 3.1 this month from 9.2 in March. Economists in a survey had forecast it would drop to 7. Readings greater than zero mean that activity increased.
