When our domestic auto industry first started, only Japanese car companies were willing to sell technology, mainly because the political, economic and time nodes coincided. At the end of 1978, China went to Europe to seek partners in the automotive industry. At that time, the automobile industry was developed in Europe, the United States and Japan, and Japan was not chosen because the Treaty of Peace and Friendship between the People's Republic of China and Japan was signed in Beijing on August 12, 1978.

Because European companies look down on the Chinese market, no car company is willing to cooperate with China, and finally only the German Volkswagen has given some opportunities.
During the Shanghai Volkswagen period, China's automobile industry was very weak, the main task was to solve the technical problems of parts manufacturing, and foreign car companies even if they did not sell technology, they still made a lot of money. At that time, the joint venture car companies imported parts and then assembled them into cars, which was equivalent to the role of us just being an "assembler".
By 1987, Santana's localization rate was still only 2.7%, and only tires, logos, radios, horns, and antennas were domestically produced in a car, and others were imported.
Japanese car companies entered China late, in order to open up the market and show their sincerity, they brought some of their own technology to China. In the 1990s, the main strategic goal of Japanese car companies was to occupy the Chinese auto market and make China a key country for strategic expansion.
In 1997, the 4G6 series technology and production line brought by the joint venture between China Aerospace Automobile and Mitsubishi have been used for decades. What Volkswagen was just starting to offer was component assembly and some inconsequential technology. Affected by such an impact of Japanese car companies, there was no way to keep up, And Volkswagen introduced the PQ34 platform and the Passat B5 sedan in 1999.
Toyota gave Tianjin FAW a Xiali, and the Japanese gave Tianjin FAW a full set of drawings and engines for Xiali, but the Xiali we built, the failure rate, fuel consumption, etc. are much worse. It is because domestic machine tools cannot keep up with the requirements of the automobile manufacturing industry, and the details are not strictly controlled, which will lead to a high failure rate. Therefore, the components of the key process are only imported equipment.
The Japanese did tell us these methods, but at that time there was no technology to produce qualified parts in China. Japan wants to seize the Chinese market, wants to sell technology to deal with European and American car companies, and compete with each other' strategies.
Thank you all for watching.
