SHANGHAI, April 25 (Reuters) - ThyssenKrupp AG expects China to yield a tenth of its global vehicle parts sales by 2010 versus less than one percent now, the head of the German industrial giant's automotive division told Reuters on Monday. ThyssenKrupp Automotive -- which accounts for about a fifth of group sales -- posted revenue of 7.31 billion euros ($9.54 billion) in 2003/04. About 1 percent of that came from Asia but no breakdown for China was available.
