Chinese Premier Wen Jiabao said the government will continue to work hard to promote social justice during his last year in office.

Income disparity and judicial injustice have incurred many complaints from the people, Wen told a press conference right after the conclusion of this year's parliamentary session.

"We must continue to press ahead with various jobs to promote the social equity and justice," Wen said.

The government will formulate an overall plan for the reform of income distribution system, and introduce a regulation on the expropriation and compensation of collectively owned rural land, Wen said.

The government will also extend the coverage of old-age pension program to the entire population, and make efforts on poverty elimination, Wen said.

On education, Wen said the government will strive to meet the target of raising government expenditure on education to 4 percent of the country's gross domestic product (GDP).
