BEIJING, Dec. 23 (Xinhua) -- A senior Chinese official has urged the country's political advisors to make more practical proposals to the government to resolve environmental pollution and other social problems.

    Jia Qinglin, Chairman of the National Committee of the Chinese People's Political Consultation Conference (CPPCC), made the remark in a letter to the CPPCC's first seminar on China's population, resources and environment development concluded in Beijing on Tuesday.

    China would have many challenges in achieving steady economic growth and social development next year, which included environmental protection, employment and resources issues, Jia said in the letter.

    Political advisors should work together and make proposals and suggestions that could serve the people and country effectively, he said.

    The seminar was attended by members of the CPPCC, China's top political advisory body, and experts from companies and research institutes.
