Speaking on an RTHK programme, Cheng said the government has always acted in accordance with the law, and the city is undergoing a transformation from chaos to order and prosperity.
She added that with stability returned and changes in the electoral system implemented, now is the time for Hong Kong to play to its strengths.
The secretary said the territory should consolidate its role as an international arbitration centre.
Cheng said the government is also trying to work out a scheme that would allow Hong Kong companies in the Greater Bay Area to use Hong Kong law for making contracts and settling disputes by arbitration.
She also said that in recent years many young people were misled into thinking they could achieve their goals by unlawful means. She said she hoped to promote the rule of law to young people, through “Vision 2030 for Rule of Law” – an initiative she is leading.
