"We are confident of achieving the main targets of economic and social development this year," Li said while briefing representatives to the 16th national congress of the All-China Federation of Trade Unions, China Daily reported Tuesday.
Li also said his government would carry out reforms and ensure employment as economic growth stabilized, adding macroeconomic policies should continue to balance growth and structural reforms.
He noted the government's continuation of a "proactive employment policy" to create more opportunities in the labor market and the promotion of social security for employers, the report said.
However, Li also warned of existing risks and challenges that could still weaken economic recovery.
Li's optimistic presentation comes following impressive numbers in the third quarter ended September.
Official data shows that China's gross domestic product grew 7.8 percent in the July-September quarter from 7.5 percent in the second quarter. Growth in the first quarter was 7.7 percent.
Separately, the consumer price index, China's main gauge of inflation, stood at 2.5 percent in the first three quarters of this year.
Li said thus far in 2013, both the GDP and inflation levels are within the government's "reasonable range," with positive changes in economic structure and increasing incomes.
Urban household disposable income rose by 7.2 percent year-on-year in real terms in the third quarter, after growth slowed to 6.4 percent in the second, data showed.
