First of all, that news is completely false. Media in China did report the efforts made by India.
Second of all, I do wonder the reason as to why their media would lie so blatantly. What could be their agenda?
Its a torture to read from Google Translate. Roughly it says the Chinese use powerful telescopes and Infrared(thermal devices?) to check out the vessel before boarding. There is a mention of the Indian helicopter but nothing of the 2 Indian warships and no sight of them anywhere nearby. More likely its a case of sour grapes and I wonder why didn't the Indian Navy offer to sent a boarding team and rightfully claim some credit, unless they arrived after the rescue operation is already underway.
