 Before the introduction of foreign technology, China conducted independent attempts to domestically develop high-speed rail technology.Some notable results included the China Star, but domestic Chinese companies lacked the technology and expertise of foreign companies, and the research process consumed a large amount of time.People's Republic of China Ministry of Railways spokesman Zhang Shuguang stated that due to historical reasons, China's overall railway technology and equipment is similar to that of developed countries' rail systems in the 1970s; high-speed rolling stock development is still in its infancy stage.
