Attempts to review the existing borders could pose a military threat to Russia, State Duma Defense Committee Chairman Vladimir Komoyedov said.
"We share a border with 16 states. These borders, including land, sea, river and lake borders, are around 61,000 kilometers long. The exclusive economic zone has an area of some nine million kilometers," Komoyedov said at a military security conference in Moscow on Thursday.
A total of 13,500 kilometers of the border with eight neighboring states are not regulated by any treaties today, he added.
In Soviet times, only 29 of the country's 79 regions were located near the border, as compared with some 50 in Russia today, Komoyedov said.
"Military threats currently facing Russia are growing more realistic and tangible," he said.
Wars have become a political instrument, the parliamentarian said, referring to the events in Yugoslavia, Iraq, Afghanistan and Syria "in which the United States was involved," Komoyedov said.
"Since 1945, the U.S. has used military force on more than 300 occasions, including some 200 instances of direct military aggression against other countries, in order to sort out problems and protect American political and economic interests abroad," he said.
