Mainland China has decreased its holdings of U.S. Treasury securities since last October, according to a report updated today  by the U.S. Treasury Department.
Since September 2008, when they eclipsed Japan, entities in mainland China have been the largest foreign owners of U.S. government debt. But, as indicated by the Treasury Department chart linked here , Chinese ownership of U.S. Treasury securities peaked in October 2010 and has declined in each of the four most recent months reported by the Treasury Department.
At the end of October 2010, China owned 1.1753 trillion in U.S. Treasury securities. That dropped to $1.1641 trillion by the end of November, $1.1601 trillion by the end of December, $1.1547 trillion by the end of January, and $1.1541 trillion by the end of February 2011.
February is the latest month for which the Treasury has estimated foreign holdings of U.S. debt.
Back in February 2001, according to historical data  reported by the Treasury, the mainland Chinese owned only $63.7 billion in U.S. debt. In the ensuing decade, the Chinese massively increased their holdings of U.S. Treasury securities, and especially in the past five years. In February 2006, China owned $318.4 billion in U.S. debt and Japan owned $656.4 billion.
