据消息人士报道，中国正在起草更严厉的《私募投资基金监督管理办法》对管理基金规模达12.7万亿元的私募基金行业加强监管。请看本报昨日的报道：

China has drafted tougher rules for its 12.7 trillion yuan (US$1.9 trillion) private fund industry, tightening scrutiny as the government reins in financial risks, according to people familiar with the matter.

The proposed new Asset Management Association of China (AMAC) rules would require hedge funds and venture capital funds to raise at least 10 million yuan before registering a product, ending the popular practice of starting with smaller amounts, the people said. Private equity and asset allocation funds would have to raise higher amounts under the plan.

The rules, which are still under discussion and could be revised, also cap investment in a single project at 20 percent of a fund’s assets and restrict co-investment by the management firm and its employees to no more than that percentage in any fund, the people said.

报道中的rein in就是“约束、控制”。例如：

He was able to rein in his temper, and then thanked the two swindlers for the lesson.

他控制住不发火，并感谢那两个骗子给了他一个教训。
