Stocks on the Chinese mainland fell for the first time in three days on Wednesday.

The retreat came after data showed that inflation exceeded government targets last month, signaling higher interest rates that may slow the world's second-biggest economy.

Jiangxi Copper Co led declines for copper producers on speculation that further monetary tightening will curb demand for industrial metals. SAIC Motor Corp dropped 2.64 percent after China's car sales decelerated in April. Huaxia Bank Co, partly owned by Deutsche Bank AG, and China Merchants Bank Co slid at least 0.9 percent after the nation's consumer prices rose 5.3 percent.

"The higher-than-expected inflation fueled investor concern (about inflation) and more tightening measures," said Li Jun, a strategist at Central China Securities Co in Shanghai.

"The economy has shown signs of a slowdown and inflationary pressure isn't easing at all. That makes it a bad scenario for the market."

The Shanghai Composite Index slipped 7.2 points to 2883.42 at the 3 pm close. The CSI 300 Index declined 0.3 percent to 3145.08. The Shanghai Composite has declined 5.7 percent from a five-month high on April 18. That's because of concern that the government will add to 10 increases in the reserve-ratio requirements for lenders and four rises in interest rates since early last year to cool inflation. The losses pared the gauge's advance this year to 2.7 percent.

China's April consumer prices exceeded the government's full-year target of 4 percent for a fourth straight month. The gain was more than the 5.2 percent median forecast in a Bloomberg survey of 30 economists and compared with a 5.4 percent increase in March.

Huaxia Bank dropped 1.1 percent to 12.18 yuan ($1.88). China Merchants Bank Co lost 0.9 percent to 14.03 yuan. The nation's new local-currency lending was 739.6 billion yuan last month, according to report from the central bank on Wednesday.

The number posted on the central bank's website compared with the median 700 billion yuan forecast in a Bloomberg survey of 20 economists.

The statistics bureau said on Wednesday that producer prices increased 6.8 percent in April, while retail sales rose 17.1 percent and industrial production gained 13.4 percent. Fixed-asset investment grew 25.4 percent in the first four months of 2011 from a year earlier, Wednesday's report showed.

The government is seeking to control consumer prices that rose to the highest in three years in March without stifling growth.

Inflation is "the most pressing problem" facing China, Vice-premier Wang Qishan said at talks in Washington this week where the US pressed for faster gains in the yuan. Economists predict one more interest-rate increase this year, according to the median forecast from a Bloomberg survey.
