"The draft law on countering corruption and two bills amending a large number of laws will be prepared," a presidential aide Larisa Brycheva told reporters.
Earlier Thursday, Medvedev signed a plan to counter corruption.
The plan envisages the creation of anti-corruption units in every branch of the Russian government, said Kremlin administration chief Sergei Naryshkin, who heads the board of the president's anti-corruption council.
Under the plan, Russian military officers, customs officials, judges and police will have to declare their property. In addition, Russia could soon establish a special disciplinary court for civil servants.
The anti-corruption plan has 14 pages and consists of four parts, a Kremlin source said.
The fight against corruption has become one of Medvedev's top priorities. Two weeks after his inauguration he signed a decree setting up a presidential anti-corruption council.
In late June, Naryshkin presented a draft national anti-corruption program. Under it, all government bodies in Russia have been asked to adopt their own anti-corruption plans by November 1.
Proposals have also been made to develop a system of incentives and safeguards for individuals who have provided reliable information about corruption, as well as mechanisms "stimulating anti-corruption behavior" among civil servants.
A relevant federal law is expected to be developed by October 1.
