Former US spy agency contractor Edward Snowden planned to meet Russian activists, lawyers as well as representatives from other groups, Moscow's Sheremetyevo airport authority said.
Snowden proposed the meeting at the international airport, a spokesman told Xinhua.
The whistleblower intended to demonstrate his attitude toward the US government's campaign against him, "as a result of which passengers of flights bound for Latin American countries are in danger," the Interfax news agency quoted an unnamed source at the airport as saying.
Russian and foreign human rights activists, lawyers and parliamentarians were invited to the meeting.
Snowden, charged by the US government with three felonies, including two under the Espionage Act, arrived at the airport June 23.
He could neither cross the Russian border nor buy another air ticket out since he does not have a Russian visa while his US passport was annulled.
On Tuesday, Venezuelan authorities said Caracas would contact the Russian government on security measures and provide humanitarian asylum to Snowden in accordance with international law.
