A more thorough explanation:

A regime is a system of rules, regulations, or government. It can refer to a particular administration or government, especially an authoritarian one. It can also refer to different types of regimes such as international regimes, which are a set of norms, rules, and policies that cover international issues, or legal regimes, which are a set of rules, policies, and norms of behavior that cover any legal issue.

• The community-property regime
• The authoritarian regime in North Korea
• The international regime for climate change
• The legal regime for intellectual property

The examples illustrate how the term "regime" can refer to different types of systems or governments. For instance, the community-property regime refers to a system of rules that govern the ownership of property between spouses. The authoritarian regime in North Korea refers to a government that exercises complete control over its citizens. The international regime for climate change refers to a set of rules and policies that countries have agreed upon to address global warming. The legal regime for intellectual property refers to a set of laws and regulations that protect the rights of creators and inventors.
