Economic ,analysts have expressed tentative optimism about the current outlook for inflation in China.It isn't,however,because April-to-May headline inflation rates declined from 8.5 to 7.7% - mainly due to a decrease in food prices.Most agreed the decline is temporary and will be pushed back up by the continuing rise in producer price inflation.Analysts were optimistic,rather,because the central bank has brandished its inflation-fighting credentials with a higher-than-normal 1% increase in the reserve ratio requirement,all while the stock market was teetering on the psychological brink of a more than 5o% drop from its last-year high.
