Altogether 5,375 proposals have been submitted to the annual session of China's top political advisory body this year, according to a report released Monday.

Among them, 4,248 have been formalized after being reviewed and 824 were listed as opinions and suggestions. Some proposals were combined with other proposals or withdrawn, according to the report read out at the closing meeting of the fourth session of the 12th National Committee of the Chinese People's Political Consultative Conference (CPPCC).

Of the total, 42 percent centered on economic affairs and 10.5 percent on political issues. Proposals on social affairs and ecological progress accounted for 31.4 percent and 9.8 percent respectively.

Political advisors proposed advancing supply-side structural reform during the 13th Five-Year Plan period (2016-2020), alleviating the tax burdens on enterprises, implementing an innovation-driven development strategy, developing e-commerce in rural areas, strengthening treatment of air, water and soil pollution, and others.

The proposals will be given to 164 government bodies to handle after the session, and the CPPCC National Committee will select key proposals to work together with related departments and individuals who make the proposals.
