BERLIN (Reuters) - U.S. President Barack Obama's plea to surplus nations to boost domestic demand was aimed "in part" at his domestic audience, German Economy Minister Rainer Bruederle said on Monday.

In a letter released before this week's G20 summit, Obama said public finance problems should be addressed in the medium term -- effectively warning that fiscal discipline should not be carried out at the expense of economic recovery.

Obama has said the highest priority for the G20 should be to strengthen the global economic recovery. However, faced with a euro zone debt crisis, several European nations, including Germany, are also focused on cutting ballooning deficits.
