Bush, Putin discuss Iran, nuclear weapons

US President George W. Bush and his Russian counterpart Vladimir Putin sat down for lunch and informal talks on ongoing nuclear disputes with North Korea and Iran, as the US leader paid an unusual visit to Moscow en route to a summit of Asian leaders. The Kremlin said in a statement after the meeting Wednesday that the two presidents discussed the Iranian nuclear program, the situation in the Middle East and nuclear nonproliferation. It also said the two confirmed their readiness for an agreement to be signed on Russia's accession to the World Trade Organization - a highly emotional issue that has taken center stage in Washington and Moscow's chilling relationship in recent months.
