MOSCOW, March 12. /ITAR-TASS/. Unilateral US sanctions against Russia might hurt other world economy players, Russian lawmakers warned on Wednesday.

"You should understand that any state in the world economy is fitted into the system of close world economic ties," head of the Committee on Economic Policy under the State Duma lower house of Russia's parliament Igor Rudensky told reporters.

"Any ill-considered move can result in unpredictable consequences and boomerang back to the initiator," Rudensky said. "Economic sanctions are a double-edged sword, and Western states should handle it very carefully."

He noted the position of European and US business communities that had urged the authorities to avoid unilateral sanctions against Russia as it would negatively impact the world economic situation in general and competitive environment in particular.

Meanwhile, Rudensky did not rule out that "possible use of economic sanctions in connection with the Ukrainian situation will bring Russians together in the solution of not only political, but also economic issues, contributing to the development of self-sufficient national economy."

For his part, head of the parliament committee on security Irina Yarovaya called US threats no other than "the wish to foil the legitimate activity of Russian officials related to securing the sovereign rights of our country and its citizens, as well as ensuring security."

On Monday, the US House of Representatives passed a resolution denouncing Russia's actions with respect to Ukraine. The resolution is of recommendatory nature.

The document urges the US president and leaders of democratic countries not to attend the G8 summit in Sochi, and consider expelling Russia from the group.

It also asks the White House administration to closely work with European allies and other states on introducing visa, financial, trade and other sanctions against high-ranking Russian officials and state-owned banks and companies.
