"As we speak, we have people working on...the so-called Hyde amendment package. So we are busily working on that, we, the US government, in preparing to submit that to the Congress," State Department spokesperson McCormack said in his briefing.

He said that the time for the Congress to ratify the deal is short.

"Admittedly, the time here is short, and there's a brief window before Congress goes out of session. As you've heard from the secretary, as well as from the White House, this administration is committed to trying to move that agreement forward," McCormack added.

The Spokesman said that senior members of Congress including Chair of the House Foreign Affairs Committee Howard Berman and Chair of the Senate Foreign Relations Committee Senator Joseph Biden have been contacted to push the deal.

"We're going to do everything we can to hold up our end of the bargain," he added.

Looking to push for an early ratification of the landmark Indo-US Civil Nuclear agreement, the White House plans to submit the 'Hyde Package' to the Congress early this week, with the goal of forcing an up-down vote by September 26, a Wall Street report had said.

McCormack also said that American companies should get a level playing field for trading with India under the nuclear agreement.

McCormack said, "We believe that American business, if allowed to compete on a level playing field, is more than capable of winning its share of business around the world...regardless of whether it's a nuclear energy or any other industry."

On whether the administration was taken aback by China's opposition to the energy waiver at the Nuclear Suppliers Group meeting in Vienna, he said the nuclear cartel had approved the move by consensus and China did not finally stand in its way.
