Imports rose by an even stronger 13.2 percent last year, also hitting a new record.

Exports have long been a mainstay of Germany’s economic strength though they have been supplemented recently by stronger domestic demand — and export growth is expected to slow this year as a result of the debt problems afflicting the 17-nation eurozone.

Germany, Europe’s biggest economy and the world’s fourth-largest, exported goods and services worth  euros 1.06 trillion ($1.4 trillion) last year, up from euros 952 billion in 2010, the Federal Statistical Office said.

Germany lost its crown as the world’s biggest exporter in 2009 to China, which has powered further ahead since. China’s exports rose 20.3 percent last year to $1.9 trillion.

German exports to countries outside the 27-nation European Union showed the strongest growth last year, expanding by 13.6 percent to €432.8 billion. Exports to other EU countries were up 9.9 percent at €627.3 billion; of those, €420.9 billion went to the eurozone, an 8.6 percent rise.

Germany’s imports rose last year to €902 billion from €797.1 billion in 2010 in a further indication that domestic demand was on the up. They broke the previous annual record of €805.8 billion, dating back to 2008.

Overall, the country’s foreign trade surplus widened slightly in 2011 to €158.1 billion from €154.9 billion.

The government has forecast that exports will grow by only 2 percent this year and economic growth of just 0.7 percent. Last year, the economy grew by 3 percent; in the fourth quarter, it is believed to have contracted by up to 0.3 percent compared with the previous three-month period — actual figures are due next week.

Monthly figures indicated softness ahead. Exports in December came in at €85.1 billion, down 4.3 percent on the previous month when accounted for seasonal and calendar factors. Imports were also down 3.8 percent at €72.1 billion and were down 3.9 percent.
