看看美国前财长保尔森的爆料

What I learned in Beijing, however, left me less than reassured myself: Russian officials had made a top-level approach to the Chinese suggesting that together they might sell big chunks of their GSE holdings to force the U.S. to use its emergency authorities to prop up these companies. The Chinese had declined to go along with the disruptive scheme, but the report was deeply troubling—heavy selling could create a sudden loss of confidence in the GSEs and shake the capital markets. I waited till I was back home and in a secure environment to inform the president.

我在北京听到的消息却令我自己绝难安心：俄罗斯官员已经与中国进行了顶层会晤，提议两个国家共同卖出大量的房利美和房地美债券，迫使美国政府动用应急权力而对两家公司提供支持。中国人已经拒绝了这一居心叵测的计划，但这一消息令人寝食难安——大量抛售可能导致人们对这两家公司突然丧失信心，对资本市场造成冲击。我一直等到回到美国后才将这一消息通知总统……

“我们曾濒临崩溃边缘，但是没有倒下。”保尔森如是说。

看了这本书，我知道了俄罗斯停止对华高端武器出口而大力扶持印度的另一个深层次原因（俄罗斯及时、果断地抛掉了所持有的美国次级债券，规避了后来的风险），也明白了中国近期继续增持美国两房债券的又一个原因——NeiJian
