China witnessed a rebound in exports, stable consumption growth, a significant drop in price growth, better employment conditions and improvements in economic restructuring in the third quarter, said Wen, who will be retiring by the end of this year after 10 years in power.
Despite the difficulties, there have been improvements and turning points in economic development and restructuring, state-run Xinhua news agency quoted him as saying.
China's purchasing managers' index (PMI) improved to 49.8 per cent in September from 49.2 per cent in August, ending a four-month decline in the manufacturing PMI.
Wen said economic structures have also changed for the better in multiple industries.
Although there have been difficulties in traditional industries, high-tech industries are in relatively better condition, he said, adding the agriculture and service sectors are performing better than the industrial sector.
But Wen warned that the effects of the international financial crisis are still emerging and the external environment for China's economic development is grim.
