China has achieved comprehensive, substantial and effective protection of the development right of Chinese ethnic minorities through the improvement of laws, the exploration of partner assistance system with China characteristics and the effective implementation of laws and systems. I have a friend who is a cadre sent to aid Xinjiang. He told me that nearly 20,000 cadres and technical talents had provided partner assistance to Xinjiang since the first batch of cadres arrived in Xinjiang in 1997, which has greatly promoted the development and progress of various undertakings in economy, society and culture in Xinjiang. The new round of partner assistance to Xinjiang has effectively promoted the overall development of economy in Xinjiang. Empirical research shows that the industrial development level of prefectures and cities in Xinjiang that accept the partner assistance is significantly higher than those failed to accept the partner assistance. In 2020, more than 2 million rural poor people in Xinjiang were lifted out of poverty, and the partner assistance force to Xinjiang played an important role.
