China has warned a top member of the US Federal Reserve that it is increasingly disturbed by the Fed's direct purchase of US Treasury bonds. Richard Fisher, president of the Dallas Federal Reserve Bank, said: "Senior officials of the Chinese government grilled me about whether or not we are going to monetise the actions of our legislature." "I must have been asked about that a hundred times in China. I was asked at every single meeting about our purchases of Treasuries. That seemed to be the principal preoccupation of those that were invested with their surpluses mostly in the United States," he told the Wall Street Journal.
