The company will now add labels to verified accounts of foreign ministers, institutional entities, ambassadors, official spokespeople, and key diplomatic leaders in 16 additional countries.
The move will provide people with context "so they can make informed decisions about what they see and how they engage on Twitter," the company said in a statement late on Thursday.
In August 2020, Twitter began applying labels to government officials' accounts in China, France, Russia, the UK and the US.
The micro-blogging platform is now adding Canada, Cuba, Ecuador, Egypt, Germany, Honduras, Indonesia, Iran, Italy, Japan, Saudi Arabia, Serbia, Spain, Thailand, Turkey, and the United Arab Emirates, beginning February 17.
"After receiving feedback on this initial action from a range of stakeholders on Wednesday, February 17, we will expand these labels to accounts from Group of Seven (G7) countries, and to a majority of countries that Twitter has attributed state-linked information operations to," Twitter informed.
Twitter said it is also updating the label text to add more specificity to the government account labels by differentiating between individuals and institutions, and expanding labels to the personal accounts of heads of state to give people on Twitter additional context.
"As the next phase of this project, we will work to apply additional labels on state-affiliated media accounts over the next several months, taking an iterative approach to ensure we capture all relevant accounts," it noted.
Twitter permanently banned former US President Donald Trump in January for inciting the deadly attack on the Capitol.
