Technology innovation from China?

There are numerous cases highlight a pattern where Chinese companies often start by replicating or adapting proven foreign technologies and business models, then iterate and localize them aggressively. This approach has been criticized as lacking original R&D and relying on intellectual property from "giant" foreign innovators. Here are some examples illustrating how Chinese companies have developed technologies or products closely modeled on foreign originals, often sparking copyright or intellectual property debates:

Deepseek comes from ChatGPT

Baidu comes from Google

WeChat comes from Whatsapp

Taobao/Alibaba comes from Amazon

BYD comes from Tesla

Xiaomi Phone comes from Apple iPhone

Weibo comes from Twitter/Facebook

China High Speed Train technology comes from Japan and France

China Aircraft C919 comes from Airbus A320
China Atomic Bomb technology comes from Russia

Historical Copying and Reverse Engineering:

China has long been characterized as a "copycat" nation that extensively reverse engineered and copied foreign technologies, especially from the U.S., Japan, France, and the Soviet Union. This copying helped Chinese firms quickly launch products and enter markets but often limited their ability to innovate beyond the original designs.

Forced Technology Transfer and Joint Ventures: 

China required many foreign companies to form joint ventures with Chinese firms as a condition for market access, which often entailed sharing proprietary technology. However, foreign firms frequently withheld core or critical technology, limiting China's ability to develop fully independent competitive products.

Evolution from Copying to Adaptation and Innovation: 

Over time, Chinese companies moved beyond mere cloning to creating products "fit for purpose" that meet local market needs at lower cost. This shift was supported by government innovation ecosystems and intense domestic competition, helping some firms like Joyoung and Huawei develop original products and technologies.

Emerging Global influence and Reverse Copying: 

More recently, Chinese tech firms have become sources of innovation themselves, with Western companies increasingly copying Chinese digital models, such as super apps (WeChat), social e-commerce, and short video platforms (TikTok). This marks a reversal of the earlier "copy-to-China" model to a "copy-from-China" phenomenon.

Intellectual Property Challenges: 

Despite progress, China still faces criticism for intellectual property theft and coercive practices to acquire foreign technology. This has benefited Chinese companies in the short term but has also been argued to hamper their long-term innovation capacity.

Cultural and Systemic Factors: 

China's innovation ecosystem is influenced by a cooperative "shanzhai山寨(copycat)" culture of open sharing and rapid iteration, which contrasts with Western IP norms. This has enabled fast-paced product development but also complicates IP enforcement and originality claims.

In summary, while much of China's technological advancement has historically relied on secondary development based on foreign "giant" research, the landscape is evolving. Chinese firms are increasingly innovating and exporting technology models, though challenges around core independent R&D, open academic environments, and genuine breakthrough innovation remain. Many Chinese "independent" developments are better described as second-generation innovations built upon foreign breakthroughs, often through reverse engineering, adaptation, or leveraging open-source and leaked technologies. This has fueled rapid industrial growth but also ongoing debates about intellectual property rights and genuine innovation capacity.

China’s military modernization has heavily relied on reverse engineering, cyber espionage, and technology transfer from Russia, the U.S., Israel, and others. Many Chinese weapons are “clones” or near-copies of foreign systems but often incorporate domestic subsystems and modifications to suit local needs. This pattern includes aircraft, missiles, drones, vehicles, and naval systems, reflecting a broad strategy of acquiring and adapting proven foreign technologies to accelerate China’s military capabilities. The following examples clearly illustrate the widespread practice of China producing copycat military systems based on foreign giants, often sparking international concern over intellectual property theft and military balance.

Russian Su-27 / Su-30 Fighter Jets becomes China J-11 / J-15 fighter Jets

China reverse-engineered Russian fighter jets to produce the J-11 and J-15, though with mixed success.

USA F-35 Fighter Jet becomes Shenyang J-35

The J-35 stealth fighter is widely considered a copy or heavily inspired by the U.S. F-35, developed partly through cyber espionage

Russian Tor-M1 SAM system becomes HQ-17 SAM system

Chinese surface-to-air missile system copied from the Russian Tor-M1

Russia S-300 air and missile defense systems becomes HQ-9

China acquired Russia’s S-300 system about six years before producing its own version, the HQ-9, which remains a primary surface-to-air missile system for the Chinese military. This was done apparently with Russian acquiescence or collaboration in some cases, such as the HQ-16 system derived from the Russian Buk-M1-2. China purchased the S-400 system from Russia in 2014 and began testing it around 2018. However, Russia reportedly delivered a simplified export version of the S-400 to China with key advanced functions blocked to protect its technological secrets and limit competition. Chinese specialists tried but failed to access these blocked functions, leading to abandonment of some efforts to fully replicate the system.
