Carrie Lam Cheng Yuet-ngor, chief executive of the Hong Kong Special Administrative Region, condemned on Friday the "Hong Kong independence" slogans that were displayed in the city's universities, adding that such remarks were in violation of the country's sovereignty, territorial integrity and development interests.

"'Hong Kong independence' runs against the 'one country, two systems' principle and the Basic Law as well as the overall and long-term interest of society," Lam said.

Lam also denounced a poster at the Education University of Hong Kong that gloated over the death of the son of the city's undersecretary for education. She said such remarks were "entirely disrespectful, against the moral values of society and coldblooded".
