China’s insurance law provisions have legal flaws that limit the scope of insurance companies’ ability to provide coverage. These flaws indicate that there is no strict distinction between the “scope of business of the insurance company” and the “scope of the insurance business”，no clear definition of the scope of the investment business and no legal provision that the insurance company can operate the non-insurance business. This has led to a detrimental effect on sustained，healthy and rapid development of the insurance industry.
