Nikkei down on weak output data, China a focus

(Updates to midsession)

TOKYO, May 30 (Reuters) - The Nikkei average fell 0.2 percent on Wednesday morning, led by electronics makers such as TDK Corp. (6762.T) after data showed industrial output unexpectedly dropped in April, raising concern about slowing U.S. demand.

Investors were taking a cautious tack after China's Ministry of Finance raised its duty on stock trading, sending the benchmark Shanghai Composite Index .SSEC down 5.7 percent before it pared some of its losses.

The Nikkei .N225 finished the morning was down 41 points 17,631.56, while the broader TOPIX index slipped 0.14 percent to 1,735.55.
