Two men found guilty of sexually assaulting underage students have been executed following the orders of China's Supreme People's Court (SPC), an SPC statement said Monday.

To address frequent sexual assaults of minors, China has given heavier punishments to offenders and warned students and parents to have greater safety awareness, the SPC said.

The two criminals include Wang Yong, who deceived schoolgirls to visit him via online chatting and raped 16 of them between 2010 and 2012 in east China's Anhui Province, causing severe damage to their physical and mental health.

Eight of the 16 girls were under 14 years of age. Wang also committed crimes of extortion.

Hu Cunbiao assaulted and robbed women and schoolgirls who were alone on the roads from 2004 to 2012 in east China's Shandong Province, and raped 11, seven of whom were under 14 years old, causing severe injuries to one girl.

Hu also acted indecently against seven children and a juvenile, and committed robbery.

The SPC urged all primary and middle schools to improve sexual and online safety education and increase awareness to protect themselves.

It also called for efforts from families, schools, society and judicial organs to prevent and reduce sexual assaults against minors.
