In a resolution, the European Parliament voted 565 in favour to 34 against, with 62 abstentions to protest the security law that Europe, Australia and the United States say would undermine the "one country, two systems" principle that governs Hong Kong's autonomy.

The European Parliament "calls on the EU and its member states to consider, in the event the new security law is applied, filing a case before the International Court of Justice," the resolution said, referring to the highest United Nations legal body and based in The Hague.
