The main reason why "the West" talk too much is because they talk about safety concerns, and actually tackle potential problems.
China doesn't, and when the proverbial shit hits the fan they simply try to cover up the result of their incompetence, too often even at the expense of human lives.
Case in point:

Another reason why "the West" talk too much is because in "the West" projects need to have a sound business model, as there isn't a dictatorship that is able to throw piles of cash at problems just to save face and resorts to industrial levels of censorship to stop these problems from being discussed.
It's easy to have successes if you use force to silence anyone who dares point out any failure.
