The annual forum, which will take place June 21 to 23, is used by the government to showcase the economy, while foreign investors attend to meet with key government officials and Russian business leaders.
"President Putin will make a speech, and the new Cabinet will be presented," Kremlin economic aide Arkady Dvorkovich said in an interview with RT television. "The new ministers will take part, so businessmen will be able to talk with the new members of the government."
Dvorkovich also said charges in government policy would be announced and discussed with investors at the forum.
The new Cabinet could be unveiled as early as Tuesday, when Dvorkovich's boss, President Dmitry Medvedev, is expected to be confirmed as prime minister, switching jobs with Putin, who will be inaugurated as president on Monday.
