In fact, there was legislation on trademarks and copyrights as early as the reform in the late Qing Dynasty, but due to the internal and external environment at that time, it was not implemented at all. There was also relevant legislation in the Republic of China until the founding of New China, and before the Cultural Revolution. The legislative work of patent law and trademark law had already begun, but it was delayed due to the Cultural Revolution. After the Cultural Revolution, our country mainly established trade cooperation relations with the United States and other countries. Under the pressure of the United States and other developed countries, China began to truly establish an intellectual property system that could be effectively implemented. The emphasis on the intellectual property system in the early 1990s was also due to China's requirements of the memorandum of understanding between the United States.

I hope my answer is helpful to you.
