The Epoch Media group spent $9.5 million on ads to spread content through the now-suspended pages and groups.
"Although the people behind this network attempted to conceal their identities and coordination, our investigation linked this activity to Epoch Media Group, a US-based media organization, and individuals in Vietnam working on its behalf," Nathaniel Gleicher, Head of Security Policy at Facebook, said in a statement on Friday.
The network called "The BL" a US-based media company part of Epoch Group repeatedly violated a number of Facebook policies, including policies against coordinated inauthentic behaviour, spam and misrepresentation.
"The BL is now banned from Facebook. We are continuing to investigate all linked networks, and will take action as appropriate if we determine they are engaged in deceptive behavior," said Gleicher.
Facebook removed 610 accounts, 89 Facebook Pages, 156 Groups and 72 Instagram accounts that originated in Vietnam and the US.
Some of these accounts used profile photos generated by AI and masqueraded as Americans to join Groups and post the BL content.
"The Page admins and account owners typically posted memes and other content about US political news and issues including impeachment, conservative ideology, political candidates, elections, trade, family values and freedom of religion," said Facebook.
Facebook also removed 39 accounts, 344 Pages, 13 Groups and 22 Instagram accounts as part of a domestic-focused network that originated in the country of Georgia.
The Page admins and account owners typically posted about domestic news and political issues such as elections, government policies, public officials, criticism of the opposition and local activist organizations.
"Although the people behind this activity attempted to conceal their identities and coordination, our investigation linked this activity to Panda, an advertising agency in Georgia, and the Georgian Dream-led government," said the company.
