The live, online dialogue will appear twice a month from late November, then once a week in 2007, said Nguyen Thi Hoa, the head of the party's website external relations department.
"We are currently working on a precise plan for these talks that will be free and open to the public, and for which we obtained the green light from the party's top leaders," she told news agency AFP.
"The highest officials from state, party and government will be invited to participate."
State media quoted a party official as saying the move was expected to create fierce debates about corruption, wastefulness and administrative reforms.
"One-way information is no longer suitable," Dao Duy Quat, the deputy head of the party central committee's Ideology and Culture Department, and chief editor of the site, told the portal Vietnam Net.
"We must make ideological work more persuasive on both ends to enhance socialist democracy in our society."
It was unclear how the leaders would respond to political issues in a country that does not tolerate criticism of its one-party regime.
Officially, state media said: "People's concerns on all political, social, cultural, security and defence issues could be good topics for these online talks."
The party which rules one of the world's last remaining communist states has shown little tolerance for any real challenges to its legitimacy in the past.
It bans all private media, blocks many political websites and routinely jails critics, last week Hanoi suspended the operations of two newspapers for a month, after they reported problems surrounding the introduction of new plastic currency notes.
