The White House denies any connection between delaying a report on China's currency policies and seeking Beijing's cooperation on new penalties against Iran for its nuclear program.
The report to Congress was due April 15, just as China's president comes to Washington for a nuclear security summit.
Treasury Secretary Timothy Geithner said Saturday he was delaying publication because several high-level international meetings in the coming months would be a better way to advance the US position.
White House economic adviser Lawrence Summers tells ABC television's "This Week" that the Iran matter isn't causing the delay and that those meetings are a good way to have a direct dialogue with the Chinese.
Some lawmakers want China branded as a currency manipulator harmful to the US economy.
