Well, according to an article in the NYT this morning a tentative agreement has been reached between the US, China, Russia and South Korea as to what to offer North Korea ($400 million in fuel oil and aid) in return for dismantling of the nuclear reactors and allowing IAEA officials back into the country. It's believed that the 5 participants will agree to it and North Korea has 60 days to accept the agreement.
Unsurprisingly, Japan has refused to offer any aid to North Korea unless the issue of the Japanese abductees has been separately resolved. (Not that Shinzo Abe has any choice since his hardline stance on North Korea and the abductee issue is what elected him). Thus, the burden of providing aid falls to the shoulders of South Korea, the US and China, and Bush will have to get Congressional approval for the aid package.
There seems to be greater efforts this time to go step-by-step, issue-by-issue, to make sure the talks don't collapse, and there are big hopes that China signing the agreement as well will ensure North Korea's compliance. However, the collapse almost collapsed on Sunday due to North Korea's energy demands and there are a lot of kinks to work out, not least the Japanese abductee issue. Hopefully though there will be more steps forward than backwards.
