According to the Wall Street Journal, according to an analysis of trade data, the process of reviewing US technology exports to China led by the US Department of Commerce has almost all received approval requests, and some crucial technology exports have increased.

According to the U.S. Department of Commerce, in 2020, U.S. exports to China totaled $125 billion, and officials requested a license for less than 0.5 percent. In this segment, the agency approved 94 percent (2,652) of applications to export technology to China, the analysis showed. In 2021, the approval rate dropped to 88%, and rejections due to incomplete information or ineligibility did not count.

The survey also found that some key semiconductor manufacturing tools are exported from China in 2021, and the Ministry of Commerce will no longer control them. The export value of such advanced technology equipment has soared to $6.9 billion from $2.6 billion in 2017.

Others have warned, though, that tougher restrictions on U.S. tech sales to China will backfire as allies such as Germany, Japan and South Korea fill the void.

Do you think it even a good idea ?

What if conflict break out and these equipment all get sanctioned ?

@tokenanalyst bro, looks like they are changing the definition again. Now to FinFet instead of naming node sizes. It also mentions withholding support and maintenance for equipment that have already been delivered.

The US plans to block sales of older chipmaking tech to China​

According to two people familiar with the administration’s plans, President Joe Biden’s approach is based around choking off access to the tools, software and support mechanisms necessary to manufacture a specific type of technology that is one of the fundamental building blocks of modern microchips: the transistor.

To achieve its objectives, the administration has elected to work to block China’s access to transistors that use a specific design called FinFET. The plans include blocking domestic exports of tools that are capable of printing chips with FinFET transistors, while also preventing the tool makers — such as Applied Materials, Lam Research and KLA — from servicing or supporting equipment they have already sold to various Chinese companies, according to the sources.

By using a specific, fundamental building block of chip design as the basis for the overall policy, the White House hopes to both tighten existing controls and avoid the pitfalls around trying to block a generation of manufacturing technology.

According to chip industry experts, using the nanometer naming conventions as the basis to block tech exports has a key problem: At one point the names referred to the size of a specific feature on a chip, but today they are just marketing terminology. Intel’s 22-nanometer manufacturing process used FinFET transistors, for example, while TSMC and Samsung didn’t adopt FinFET designs until they produced chips with a 14-nanometer process or 16-nanometer process.
