Sounds a lot like the exaggerated Bolloywood scripts that came out of India around the 'surgical strikes', Balakot attacks and F-16 down.
Were it not for clear cut evidence and Pakistan openly taking local and foreign media to the locations and satellite imagery analysis by independent analysts, the Indian narrative would have stuck.
The Chinese need to learn from Pakistan's experience and find ways to provide their narrative and information to an international audience. Given that the US led West is already against China and hoping to build up India against China, India's narrative, no matter how exaggerated or flawed, will find plenty of amplification in the West, especially given the lack of a quality Chinese narrative.
I still believe that China banning defence.pk in China was an extremely bad move. Whilst not the only platform, it would have played a role (with Chinese posters that can communicate and contribute well in English) in helping counter anti-China narratives.
