> The Basic Law says Chinese laws can't be applied in Hong Kong unless they are listed in a section called Annex III - there are already a few listed there, mostly uncontroversial and around foreign policy.
These laws can be introduced by decree - which means they bypass the city's parliament. Critics say the introduction of the law this way amounts to a breach of the "one country, two systems" principle, which is so important to Hong Kong - but clearly it is technically possible to do this.
