The consumer price index in China rose 2.7% year-on-year in June, in line with expectations from a Reuters poll.
One strategist said the rise in consumer prices in China may abate in the near future.
"The pork price pressure would wane somewhat in the second half, I believe, and other food prices may have a similar trend," Daniel So, strategist at CMB International Securities, told CNBC's "Street Signs" on Wednesday.
Others, however, warn that the situation around pork prices may get worse. A decline in pork supply caused by an outbreak of African swine fever has been driving up prices of food in China. In June, food prices in June increased 8.3% year-on-year, higher than the previous month's figure of 7.7%.
Darin Friedrichs, senior Asia commodity analyst at INTL FCStone, told CNBC's "Squawk Box" on Wednesday that actual numbers for culled pigs are probably higher than official government statistics of about 20% to 25% of the hog population in China.
"Realistically the number's probably closer to 50% or even higher at this point," he said. "The government is estimating perhaps 70% inflation in the second half of the year, but given that they don't seem to have (a) very good handle on it and given that it seems to be widely underreported, obviously we could expect that number to go much higher."

Fed Chair Powell is scheduled to testify in front of the House Financial Services Committee on Wednesday.

"We expect Powell to reiterate both the Fed's belief that the case for more accommodative monetary policy has strengthened and its commitment to ensuring the US economic expansion does not falter," Joseph Capurso, senior currency strategist at Commonwealth Bank of Australia, wrote in a note.
