The eurozone economy grew by 0.6% in the three months to the end of June compared with the early part of the year, official data has shown. Between January and March, the economy of the 19-member bloc increased 0.5%.
In the second quarter, the eurozone economy grew at twice the speed of the UK's, which suffered a "notable slowdown" in the first half of the year.
The figure is just below the 0.65% seen in the US in the same period. The acceleration in output growth confirms the sound recovery of the eurozone after data released on Monday showed the bloc in June recorded its lowest unemployment rate since 2009.
Christian Jaccarini, an economist with London-based think tank the Centre for Economics and Business Research (CEBR), said this and other data suggested that the eurozone was moving in the right direction.
"Moving forward, CEBR forecasts the eurozone to expand by 1.9% in 2017, revised up from our earlier forecasts," he added.
