CRAWFORD, Texas (AFP) - The White House on Tuesday flatly rejected Russian charges that NATO was being "biased" in the Georgia conflict, and renewed US demands that Moscow withdraw its forces immediately. ADVERTISEMENT "I would expect them to begin an immediate withdrawal, which is their commitment. We want them to honor their commitment," spokesman Gordon Johndroe said as US President George W. Bush watched the crisis from his Texas ranch. Johndroe rejected Russian Foreign Minister Sergei Lavrov's contention that NATO's new statement on the conflict in Georgia was "unobjective and biased" against Moscow and that Russia's withdrawal may take three or four days. "It didn't take them really three or four days to get into Georgia. And it really shouldn't take them three or four days to get out," the spokesman said, adding that Lavrov was "entitled to his opinions." But "Russia invaded a neighbor, has said it would withdraw, hasn't withdrawn. I think they need to; so does the rest of the international community. So nothing really one-sided about that," said Johndroe. "I think the United States and our NATO allies are staying united. And that was made clear in Brussels today. So I think the comments that he makes are inconsistent with the rest of the worldview," he added. Lavrov earlier had criticized NATO's statement on the conflict in Georgia as "unobjective and biased" and accused the alliance of whitewashing a "criminal regime." "The (NATO) declaration above all appears unobjective and biased because there's not a word about how all this started, why it happened, who started the aggressive action and who armed Georgia," Lavrov said at a press conference called in response to the NATO statement. He referred to a statement by NATO foreign ministers in Brussels that condemned Russian military action as "disproportionate and inconsistent" with Moscow's peacekeeping role and said the alliance could not carry on "business as usual" with Moscow. One day after Democratic Senator Joseph Biden, a possible vice presidential choice for his party in the November elections, said he would work to give Georgia one billion dollars in aid, Johndroe said any figure was "premature." "It's premature for me to put a dollar figure on it now. It will be a substantial commitment by the United States to Georgia," he said. "It's going to be a substantial commitment by the United States to Georgia for, one, immediate humanitarian assistance and then, two, reconstruction of their infrastructure that has been needlessly destroyed, and then, also, the need to help them rebuild their military," said Johndroe. Biden said upon his return from Georgia on Monday that he would work with the White House to provide Georgia with one billion dollars in emergency aid. "This money will help the people of Georgia recover from the damage that has been inflicted on their economy and send a clear message that the United States will not abandon this young democracy," said Biden, head of the Senate Foreign Relations Committee. The US Congress reconvenes on September 8 after a summer break. Biden hoped the planned US commitment would be matched by other nations.
