"We will continue rendering aid to the PNA's attempts to establish statehood, the strengthening of its power structures, and the resolution of its social-economic problems," Vladimir Putin said in a message to PNA leader Mahmoud Abbas.
The message was read out by Alexander Yakovenko, a Russian deputy foreign minister, at a ceremony to mark the International Day of Solidarity with the Palestinian People.
Yakovenko said the Russian Foreign Ministry is convinced that inter-Palestinian negotiations are necessary for Palestinian-Israeli agreements to be a success.
"Russia will continue dialogue with different Palestinian forces in the name of establishing peace and harmony in the region," he said.
In June, Islamist group Hamas seized control of the Gaza Strip after a series of clashes with Palestinian President Mahmoud Abbas' Fatah movement.
Russian Foreign Minister Sergei Lavrov welcomed on Wednesday the results of Tuesday's Mideast peace conference, which was held in the United States and attended by 44 nations, and announced that Moscow would host the next conference.
Talks between Israelis and Palestinians have been stalled for almost seven years, with no progress made on key issues such as the borders established before the Arab-Israeli war of 1967, Palestinian claims to East Jerusalem, the plight of Palestinian refugees, and Israeli settlements in the West Bank.
