BEIJING -- The efficiency of Chinese courts has been improved by 20 percent since 2013, the Supreme People's Court (SPC) announced Monday.

The SPC Monday released two white papers on judicial reform and court transparency from 2013 to 2016, recording progress made in fields including judicial accountability, trial mechanism and adjudicative power operation.

According to the SPC, over 26 million court documents have been posted on China Judgement Online, the court document website, and the site has clocked up six billion hits by users from over 200 countries and regions.

China's courts have improved the way in which they protect human rights, preventing and correcting cases in which people were unjustly, falsely or wrongly charged or sentenced.

From 2013 to 2016, courts nationwide overturned 34 cases, involving 54 people, deemed to be miscarriage of justice, according to the SPC.

To improve litigation, nearly all courts in China have established supporting systems, the SPC said.

The top court also pledged to improve how cases are filed and legal aid accessed.
