The Administrative Procedure Law of the People's Republic of China is the primary law governing regulatory law in China. It sets out the general principles and procedures for administrative decision-making, including the rights and obligations of administrative agencies and the rights of citizens and organizations.

Non-governmental organizations are not a type of administrative agency in China. Administrative agencies are government entities that have the power to make and enforce regulations.

The National People's Congress has a number of roles in regulatory law, including enacting laws and regulations, overseeing the implementation of laws and regulations, and appointing and removing administrative officials.

The State Council has a number of roles in regulatory law, including implementing laws and regulations, drafting laws and regulations, and overseeing the implementation of laws and regulations.

The courts have a number of roles in regulatory law, including interpreting laws and regulations, enforcing laws and regulations, and reviewing administrative decisions.

The principle of legality in regulatory law requires that administrative agencies must act in accordance with the law, citizens and organizations have the right to challenge administrative decisions, and administrative agencies must be transparent and accountable.

The principle of proportionality in regulatory law requires that administrative agencies must use the least restrictive means to achieve their objectives, consider the costs and benefits of their actions, and take into account the individual circumstances of the case.

The principle of transparency in regulatory law requires that administrative agencies must be open and transparent in their decision-making, provide citizens and organizations with access to information, and consult with citizens and organizations before making decisions.

The principle of accountability in regulatory law requires that administrative agencies must be held accountable for their actions, citizens and organizations have the right to seek redress for violations of their rights, and administrative agencies must have effective internal control systems.

The public has the right to participate in the regulatory process, the right to access information about regulatory decisions, and the right to challenge regulatory decisions.

The main challenges facing regulatory law in China include the lack of a comprehensive regulatory framework, the lack of transparency and accountability in regulatory decision-making, and the lack of public participation in the regulatory process.

Some of the recent developments in regulatory law in China include the adoption of the new Administrative Procedure Law, the establishment of the National Regulatory Commission, and the launch of the Regulatory Sandbox initiative.

The future of regulatory law in China is likely to see the development of a more comprehensive and systematic regulatory framework, increased transparency and accountability in regulatory decision-making, and greater responsiveness to the needs of the public.

Some of the key issues that need to be addressed in order to improve regulatory law in China include the need for a more comprehensive regulatory framework, greater transparency and accountability in regulatory decision-making, and greater public participation in the regulatory process.

Some of the best practices in regulatory law that China can learn from other countries include the use of risk-based regulation, the use of performance-based regulation, and the use of co-regulation.
