EU says Hong Kong decision damages trust with China - Borrell

European Union governments expressed "grave concern" on Friday over China's security law for Hong Kong, the EU's top diplomat Josep Borrell said following a meeting of the bloc's 27 foreign ministers.

"We express our grave concern at the steps taken by China ... we believe that this seriously risks undermining the one country two systems principle," Borrell said.

"Our relationship with China is based on mutual respect and trust but this decision calls this into question," Borrell told reporters.
