China and Taiwan signed a cooperation agreement in 2010 for the mutual recognition of intellectual property rights. However, there are significant differences in the regulations and implementation of variety rights protection between the two countries. Guo Huaren, an honorary professor at National Taiwan University, suggests that variety rights holders should understand the differences before making international arrangements, and the government should actively educate them on the gaps. The outflow of high-quality crop varieties from Taiwan to China has already occurred, and the protection of variety rights needs to be considered to prevent further loss.
