Washington (CNN) – Russian President Dmitry Medvedev will meet U.S. President Barack Obama for talks at the White House on Thursday after taking a technology tour of California a day earlier.
After the leaders have lunch, Obama will attend a U.S.-Russia business summit at the U.S. Chamber of Commerce.
On Wednesday, Medvedev visited Cisco Systems for the company's announcement of a $1 billion investment in Russian projects. He sent his first Twitter message after the meeting.
"Greetings to everyone, I'm at Twitter and this is my first message," the Russian leader tweeted from Twitter headquarters in San Francisco. Medvedev also posted a photograph of the "view outside my hotel window" in San Francisco and another of himself greeting Twitter employees from the new @KremlinRussia account.
