The United States on Friday said "every single commitment" in the 123 agreement is binding but made it clear that Washington cannot "compel" American companies to offer technology or supply fuel or compel other governments to do things in a particular way.

US Ambassador to India David C Mulford said the 123 agreement is expected to be signed by the two countries during the visit of Secretary of State Condoleezza Rice [Images] to India which is likely to take place in a few days.

"In the 123 agreement, which is going to be a law, every single commitment is binding," an elated Mulford told reporters hours after the deal crossed the last hurdle in the form of Congressional nod.

He said the commitments under the 123 agreement have been "preserved" in the Congressional process as no amendments have been made to its content.

The envoy said the commitments in the 123 agreement will be "faithfully honoured".

When referred to the riders sought to be attached to the nuclear deal, Mulford said "if you have any specific questions, you should refer to the 123 agreement."
