Twitter chief Dick Costolo met on Friday with US Secretary of State Hillary Clinton as Internet age technologies play growing roles in world affairs.
"Pleasure to meet with Secretary Clinton and the @statedept team today," Costolo said in a "tweet" he fired off at the popular one-to-many text messaging service.
San Francisco-based Twitter did not provide details of what Costolo discussed with Clinton during their meeting in Wasington, D.C.
Twitter has become a powerful tool for political activists around the world, giving people a way to coordinate protests and quickly spread word of setbacks, victories or other developments in campaigns.
The US State Department in February held its first Twitter briefing in Spanish, as part of its policy of using new social media to reach out to the international community.
The State Department has Twitter feeds in 11 languages: English, Arabic, Turkish, Chinese, Farsi, French, Hindi, Portuguese, Russian, Spanish, and Urdu.
"These social media accounts are conduits for the US Department of State to inform and engage individuals around the world on American foreign policy issues," the department has publicly stated.
"They also support the department's 21st Century Statecraft efforts, complementing traditional foreign policy by harnessing the digital networks and technologies of an interconnected world," it added.
