German gross domestic product (GDP) could grow by as much as three per cent in 2010, as positive quarterly figures have stoked optimism in Europe's largest economy, Die Welt newspaper reported on Sunday, citing Economy Ministry officials. Statistics released on Friday showed that the German economy had grown by 2.2 per cent in the second quarter, much more than expected and the fastest quarterly increase since reunification in 1990, according to dpa. Germany now appears to be pulling strongly away from the recession of 2009, when the economy shrank by nearly 5 per cent. The official government projection for the year remains at 1.4 per cent growth.
