Google closed 210 YouTube channels involved in organized false propaganda related to Hong Kong protests, Bloomberg and Reuters reported.

Twitter and Facebook made similar action on the 19th, and YouTube also launched a crackdown on the alleged propaganda channel.

Google hasn't specified which account it's closed to.

However, he explained that Twitter and Facebook found accounts that matched recent observations and actions related to China.

Google also did not say where these channels came from.

The State Department said, "We are deeply concerned about China's attempts to manipulate public opinion by disseminating fake information about the situation in Hong Kong."

The Chinese embassy did not respond to requests for comment, Reuters said.

Twitter and Facebook have recently removed hundreds of accounts that have been linked with the Chinese government, saying they were sending a message to lessen the justification for Hong Kong protests.

Twitter also said it would not accept advertising from state news media.

But YouTube has no plans to change its advertising policy, but says it will expand the labeling of nationally-supported news media in China.

According to Reuters, YouTube shows that it is not responsible for Xinhua's or CCTV's services, but does not take such measures to the People's Daily, China Daily and the Global Times.

YouTube, along with Google Search, Twitter, and Facebook, is not currently available in China.
