Huawei's new MateBook Fold laptop is sparking discussion about the impact of US sanctions on Chinese tech companies. The laptop uses a 7nm chip made by Semiconductor Manufacturing International Corp (SMIC), which is considered old technology compared to Taiwan Semiconductor Manufacturing Co's upcoming 2nm chips.

*Key Points:*

- *US Sanctions Impact*: The US has imposed restrictions on China's access to cutting-edge chipmaking tools and AI chips, hindering its progress in advanced semiconductor development.

- *SMIC's Limitations*: SMIC has not yet achieved a 5nm-equivalent node that can be produced at scale, according to TechInsights, highlighting the impact of US technology controls.

- *Huawei's Progress*: Despite US sanctions, Huawei has made progress in developing its own chips, including the 7nm chip used in its Mate 60 Pro, which surprised US officials in 2023.

- *China's Tech Self-Reliance*: The MateBook Fold reflects Beijing's push for tech self-reliance amid US-led restrictions, with Huawei and SMIC playing key roles in China's advanced chipmaking efforts [1].

*Implications:*

- *Global Tech Competition*: The US-China tech rivalry is intensifying, with the US viewing China as a key rival in artificial intelligence and taking steps to limit its access to advanced technology.

- *Impact on Chinese Tech Companies*: US sanctions may hinder Chinese tech companies' ability to compete with global leaders, potentially affecting their growth and innovation [1].
