Singh, who struck the deal with Bush in July 2005 and has encountered strong opposition from the Left allies now threatening to withdraw support to the government, will undertake a two-hour early morning drive for his meeting with Bush in Toya, about 200 km from here, a place where all the G-8 leaders are staying.

The meeting is slated before 0800 hours after which the Prime Minister will have a breakfast meeting with G-8 as part of the O-5 outreach countries summit with them. He will review the progress on the deal with the President.

Singh may brief Bush on the recent political developments in which he has won new and crucial political support for the deal at home in the face of severe opposition from the Left and the possibility of overcoming problems in Parliament from the Left action.

The government's plans on approaching the International Atomic Energy Watchdog (IAEA) for securing an India-specific safeguards agreement and moves for taking the matter to the NSG are expected to figure in the discussions with Bush.

The Prime Minister has pointed out that the US was committed once India takes the decision the US will have to fulfil its promises. It is a public commitment on their part, the Prime Minister said yesterday. He had also said the government would approach the IAEA "very soon" and once it takes the decision the process in this regard was expected to move "pretty fast".

On Wednesday, the Prime Minister will also be meeting the new Russian President Dmitry Medvedev and Japanese Prime Minister Yasuo Fukuda.

He will also interact with German Chancellor Angela Merkel, French President Nicholas Sarokozy, British premier Gordon Brown and South African President Thabo Mbeki, who are all part of the NSG from where India should get a clear exemption for conducting nuclear commerce with other countries.

Singh told reporters accompanying him to Japan on Monday that during the bilateral discussions the civil nuclear cooperation agreement would figure in these discussions.

"Our attempt has been and I will reinforce that effort to impress upon the global leaders that India's civil nuclear cooperation agreement as and when it goes before the IAEA and the NSG that we obviously seek the support of the world community in both these fora," he had said.

The Prime Minister is confident that China would not be a problem in the way of civil nuclear cooperation though he does not have a firm assurance from Beijing as of now. His meeting with President Hu Jintao on Tuesday may have led to further understanding of the Chinese position.
