Martial law was introduced in Georgia on August 9, the day after Georgian troops attacked South Ossetia, and then extended on August 23 until September 8.
"Martial law regulations are causing certain problems for the country's economy. They limit export and import operations, tourism, and transit," Georgian Parliamentary Speaker David Bakradze said, explaining the decision.
He added that parliament had declared a state of emergency "in the occupied territories."
The Russian prime minister claimed on Tuesday that there were no Russian troops in Georgia, including in Poti.
"There are no Russian troops on Georgian soil - there are only peacekeeping forces," Vladimir Putin said.
Georgia launched its assault on South Ossetia in an attempt to regain control over the republic, which split from Tbilisi in the early 1990s. Georgian peacekeepers and regular troops also attacked Russian peacekeepers stationed in the region.
Moscow subsequently launched an operation to "force Georgia to accept peace." The operation was concluded on August 12.
