BEIJING - The White House on Sunday denied speculation that the US delayed a report on China's currency policy in exchange for support on fresh sanctions against Iran.

US President Barack Obama's adviser on economic issues Lawrence Summers told ABC TV that the postponement of the report was "part of the US' international economic dialogue", even as he denied speculation that the delay was aimed at eliciting China's cooperation on sanctions against Iran.

The report to Congress, which is likely to label China an exchange rate manipulator, was due April 15 but will reportedly be delayed.
