Washington: As the reconciliation process on the final legislation to implement the Indo-US nuclear deal moved into top gear, Senate Majority Leader Bill Frist assured Prime Minister Manmohan Singh that lawmakers are 'working on' issues of concern to India and hoped that Congressional action on it would be completed this week.

The Bush administration also said there is 'flexibility' and 'willingness' on the part of lawmakers to look at ways of expressing their views without making it difficult to carry out the accord in the way that it was negotiated.

The appointed Conferees of the House and Senate held their first formal meeting yesterday to work on the language of the final legislation.

Frist, who telephoned Prime Minister Singh last evening, assured the Indian leader that one of his top priorities for the remainder of this Congress is to enact the legislation and said he was confident that we will be able to complete Congressional action on it this week.

 Singh stressed that there are a number of provisions in the House and Senate-passed bills that are problematic for the India because they depart from the understanding reached with President George W Bush on this issue on July 18, 2005.

"We discussed several of these provisions and I assured him that the conferees are well aware of the Indian government's concerns," Frist said, adding that legislators are working on the issues of concern to India.

 Assistant Secretary of State for South and Central Asia Richard Boucher said efforts are underway to address India's concerns over some provisions of the legislation.

"There are sections in this bill that people in The (Capitol) Hill feel very strongly about but we found a certain flexibility, a certain willingness to look at other ways of expressing those views," Boucher said.
