Reason:
1. In a sovereign and equal international society, the legislative powers of countries are independent of each other, and laws enacted by countries with different social systems are inevitably different in nature, and differences in content and conflicts between them are inevitable.
2. Laws are not only bound by class, but also influenced by a country's economy, culture, history, religion, habits and other social factors, so there will be differences between countries with the same social system.
3. Within a country, its legislative power is also exercised by multiple departments, so the laws formulated by different departments will also conflict.
4. Laws are always made on the basis of certain social relations and legislators' limited predictions on the development and changes of social relations. Therefore, with the development and change of social relations, the laws implemented in some fields will also change accordingly. In this way, there will be differences and conflicts between the new law and the old law.
