"Last week’s decision by the Bank of Japan to double the country’s money supply over the next two years through massive purchases of long-term government bonds will both fuel the deepening global economic crisis and stimulate further attacks on the Japanese working class.
Japan has not only joined the program of “quantitative easing” being carried out by other major central banks, it has done so at twice the rate being undertaken by the US Federal Reserve Board.
Economists in China, who advise the country’s central bank, are reported to be “livid” over the decision, criticising the BoJ’s actions as starting a currency war. They have called on the Peoples Bank of China (PBoC) to respond by taking action to push down the value of the yuan."
