Chinese authorities are cracking down on academic fraud after an international medical journal retracted 107 Chinese-authored papers from the past five years, in the biggest case to date of fake peer reviews to endorse research, the Financial Times reports. Springer, publisher of the journal Tumor Biology, said the retractions were made because the peer review process had been “deliberately compromised by fabricated peer reviewer reports.” China’s ministry of science and technology said this week that the incident had “seriously harmed the international reputation of our country’s scientific research and the dignity of Chinese scientists at large.” It vowed a “no tolerance” approach to academic fraud. The government pledged to investigate the papers’ authors and may strip them of their academic roles. All grant funding to the academics involved has been halted. China has become the second-biggest source of academic publications globally.
