"The domestically produced C919 made its first international flight, and anti-China forces claimed that the core equipment was made in a foreign country"
Wen Zhanhai. 
The C919 passenger aircraft, a magnificent masterpiece that marks the rise of China's aviation manufacturing industry, has finally stepped on the international stage and ushered in a historic moment. However, at this proud moment, some foreign anti-China forces have impatiently started a smear offensive against C919 in an attempt to belittle the achievements of China's aviation industry.
A blogger named "Collin Koh" even took out a chart from a few years ago, claiming that the core equipment of the C919 was made in a foreign country, as if to prove that this aircraft was a product of "made in all countries". The figure shows that except for a few components such as tail, wings, flaps, and radomes, which are domestically produced, other important systems and components are provided by the United States and other countries. This division makes the C919 seem like an international hodgepodge.
However, we need to look at these accusations rationally. First of all, it is the norm in the industry for commercial aircraft to adopt the integration scheme of international first-class merchants. Take the Boeing airliner in the United States as an example, although it is widely advertised as "made in the United States", many of its subsystems actually come from the world's leading companies. This globally collaborative manufacturing model is not the exception, but a common practice in the industry.
The reason why C919 chooses international first-class merchants is to be able to better "go out" and enter the international market. This does not mean that China cannot develop and manufacture these components in-house, but rather that it is based on commercial interests. Boeing airliners also have the participation of international first-class companies, and even some parts are made in China. According to the logic of the anti-China forces, the Boeing airliner should also be "made in all countries".
What's more, some of the subsystems that have been blamed are actually major breakthroughs in the field of science and technology for China. The high-intensity radiation field protection system of C919 is completed by domestic scientific research institutes, and the wing part that is understated is completed with the support of leading science and technology of China's scientific researchers, using "random spectrum frequency conversion control technology", and the error range is leading in the world.
What's even more interesting is that we have managed to build a large transport aircraft like the Y-20, proving that we are more than capable of providing domestic backups for a passenger aircraft of the C919 class. Therefore, C919 chooses international first-class businessmen, not because technology cannot be replaced, but to promote the "globalization" of the aircraft and reduce the barriers to the international market.
Therefore, the anti-China forces' attack on the C919 is nothing more than ignorance and misunderstanding of China's aviation industry. Their accusations not only expose their ignorance of the aviation manufacturing industry, but also highlight the correctness and importance of C919 as a representative of China's aviation industry. Making these anti-China forces make such a fuss without understanding the situation only proves the correctness and necessity of the C919 airliner going abroad.
At this moment full of challenges and opportunities, let us applaud C919, an outstanding representative of China's aviation industry, and look forward to it spreading its wings on the international stage and winning more applause and respect for China's aviation industry!
