China's exports dropped 0.3 percent in September from a year earlier, against expectations of a 6 percent rise, data showed on Saturday.
"September CPI inflation gained more momentum on seasonal factors and a low base effect from last year," said Li Huiyong, an economist at Shenyin & Wanguo Securities in Shanghai.
"But we think the inflation situation is still under well control and will not be a concern this year, especially when the economy is struggling with over-capacity problems."

Still, producer prices have fallen for 19th consecutive months. China's annual economic growth is forecast to have accelerated to 7.8 percent in the third quarter from 7.5 percent in the second quarter, the Reuters poll showed.
Beijing has a growth target of 7.5 percent for 2013, which would be the weakest rate in more than 20 years, and has repeatedly said it would accept slower growth as it tries to restructure the economy to be driven by consumer demand, rather than investment, credit and exports.
