Facebook unveiled new plans Monday to fight 2020 election interference. It will clearly label news that comes from state-owned media, and will give greater transparency for the origins of Facebook pages. And it has already found interference coming from authoritarian regimes overseas.

In an interview with NBC News, Facebook CEO Mark Zuckerberg said the company has thwarted new interference campaigns from Russia and Iran that it regards as the groundwork for future manipulation efforts.

Zuckerberg added that China has also been found to have tried to interfere in various elections, but that the company has been able to find and stop them.
