Mainland China's holdings of US Treasury bonds fell for the first time in 11 months to 763.5 billion dollars in April, US government data showed Monday.
The April figure, a drop from March's 767.9 billion dollars, was the lowest since the holdings started building up in June 2008, the US Treasury said in its monthly international capital data report.
The figures do not include the holdings of Hong Kong, China's special administration region, which climbed to 80.9 billion dollars in April from 78.9 billion dollars the previous month.
But the latest statistics showed China sitting comfortably as the top holder of Treasury bonds despite years of trying to diversify its reserves away from the US dollar.
Japan is the second-largest holder of US bonds, at 685.9 billion dollars in April.
