U.S. President George W. Bush has urged Russia not to recognize Georgia''s two breakaway regions as independent, and has sent his deputy Dick Cheney to Georgia in a show of U.S. support.

Both houses of Russia''s parliament voted unanimously on Monday in favor of a resolution asking President Dmitry Medvedev to recognize the independence of Abkhazia and South Ossetia, following requests from the leaders of both breakaway republics.

Bush said in a statement from his ranch in Texas, "I call on Russia''s leadership to meet its commitments and not recognize these separatist regions."

"Georgia''s territorial integrity and borders must command the same respect as every other nation''s, including Russia''s," he said.

Medvedev has yet to respond to parliament''s request, but earlier said that South Ossetians and Abkhazians should be given a say in their status. Russian officials have said Georgia lost its right to the two regions after launching a military offensive that devastated South Ossetia.

Bush said recognition of the regions would be "inconsistent with unanimously approved United Nations Security Resolutions that Russia has consistently voted for in the past."

White House spokesman Tony Fratto told reporters on Monday that Dick Cheney would visit Georgia in early September.

"The Vice President will be delivering... the word of America''s support, and also consulting on how these leaders in the region see the future playing out," he said.
