China's bout of deflation persisted in April, as consumer prices fell 1.5 percent from elevated levels a year earlier, but analysts said they expect prices to start heading upward later in the year.

The central bank, meanwhile, reported Monday that new bank lending in April was less than a third that of the month before, as lenders slowed the flow of credit aimed at stimulating flagging growth.

The consumer price index, which is heavily weighted toward food, fell for the third month in a row after declining 1.2 percent in March and 1.6 percent in February, the National Statistics Bureau reported.

Food prices fell 1.3 percent, with prices for meat falling 13.5 percent, the bureau said in a statement on its Web site.

Prices for pork, China's staple meat, plunged 28.6 percent in April after peaking a year ago following an outbreak of blue ear disease, also known as porcine reproductive and respiratory syndrome, that prompted many farmers to stop raising pigs.

Producer prices, a key indicator of price trends, fell 6.6 percent in April from a year earlier, compared with 6.0 percent in March, thanks largely to lower energy costs.

Overall, costs for fuel and raw materials fell 9.6 percent in April, the report said.

While a protracted bout of deflation would be unwelcome, April's decline was expected, and the data initially helped push share prices higher Monday.

But the benchmark Shanghai Composite Index fell back later in the day as investors sold shares to cash in on recent gains, ending 1.8 percent lower at 2,579.75.

Deflation is expected to persist in China for several more months due to excess inventory in many industries amid the global economic downturn. Sharp declines in crude oil prices and costs for other commodities will ensure that.

But signs of economic recovery in China suggest a reduced risk for a prolonged bout of lower prices that could drag growth lower if consumers put off purchases in expectation of lower prices, forcing companies to cut wages and investment, economists say.

The government has pumped billions of dollars into construction projects and other spending aimed at stimulating demand and propping up growth.

Although growth dipped to 6.1 percent in January-March, its lowest level in at least a decade, improvements in manufacturing, auto sales and real estate data are seen as signs the strategy has begun to work, despite persistently weak demand for Chinese exports in overseas markets.

"Deflationary concerns appear to be subsiding as the economy shows signs of recovery," Jing Ulrich, chairwoman for China equities at J.P.Morgan said in a report to clients.

"Consumer prices should show an uptrend in the second half of the year. Importantly, expectations of rising prices in the future will encourage consumer spending," Ulrich said.

Government moves to liberalize controls on utility rates and fuel prices, which have been kept lower than global levels, will also push prices higher, she said.

"It's too early to say, but we are worried that prices will begin to rebound by midyear, leading to inflation" rather than deflation, said Gao Yi, an analyst at Oriental Securities in Shanghai.

Lenders already have begun to slow the flow of credit to government stimulus projects: the 591.8 billion yuan ($87 billion) in new loans in April was down sharply from 1.9 trillion yuan ($278 billion) the month before, though up 27 percent from a year earlier.

The sharp drop was expected after banks accelerated lending in the first quarter of the year to support a 4 trillion yuan ($586 billion) stimulus package.

The central bank says it will keep monetary policy loose to ensure ample liquidity in coming months. But in its first-quarter report, issued last week, it noted growing concern over the risks of a surge in bad debt and factory overcapacity due to excess lending.

"Commercial banks seem to be caught between a rock and a hard place. The central bank has asked for more lending and also better credit quality," Sherman Chan, an economist for Moody's Economy.com, said in a report issued last week.
