Hong Kong's leader urged an immediate end to independence debates in the Chinese-ruled global financial hub Tuesday, warning that the issue was harming the city's relationship with Beijing's Communist Party leaders.

Insisting that the government did not want to intervene on university campuses, Chief Executive Carrie Lam said the campaign was "organized and systematic" rather than simply an issue of freedom of speech.

"This has already deviated from the so-called, Why aren't we able to talk about this? point of view. It is clearly attacking 'one country, two systems' ... and destroying the relationship between Beijing and Hong Kong," Lam said.
