It's a mistake to think that what goes on in Hong Kong applies to mainland China. It seems from the article that the news was directly about Hong Kong, and in that case it's a promotion of certain freedom, available in a specific region, which can somewhat appease the public without any major changes for most of the country.
Obviously, some freedom in Hong Kong is good news, but it's nothing new, and the rest of the country is likely to continue living with the ongoing restriction and an illusion of financial freedom because you can hypothetically go to Hong Kong and enjoy it there.
Hong Kong has many differences than China mainland. Different regime, politics, economics models which are better than in China Mainland. The power in Hong Kong belongs to their citizens and their vote rights, not like in China mainland with serious centralized power in Xi Ping, a single man. China mainland is like Russia under the foot of a single man Putin.
Because of freedom and a regime which serves citizen benefits, Hong Kong can adapt better with modern technologies and have new adaptive policies to help its economy.
In China mainland or Russia, if they want to change anything, they can do it after an hour with a perfect 100% supported votes in their Congresses.
