Two officials at leading Communist Party bodies have given interviews in recent days warning - for the first time - that Beijing may use its $1.33 trillion (£658bn) of foreign reserves as a political weapon to counter pressure from the US Congress.
...He Fan, an official at the Chinese Academy of Social Sciences, went even further today, letting it be known that Beijing had the power to set off a dollar collapse if it choose to do so.
"China has accumulated a large sum of US dollars. Such a big sum, of which a considerable portion is in US treasury bonds, contributes a great deal to maintaining the position of the dollar as a reserve currency. Russia, Switzerland, and several other countries have reduced the their dollar holdings.
"China is unlikely to follow suit as long as the yuan's exchange rate is stable against the dollar. The Chinese central bank will be forced to sell dollars once the yuan appreciated dramatically, which might lead to a mass depreciation of the dollar," he told China Daily.
