[Wen / observer net bear detached] local time on November 18th, Reuters quoted people familiar with the matter as saying that the upgrading and transformation plan of Korean enterprise SK Hynix Wuxi factory is in danger, because American officials do not allow ASMA EUV (extreme ultraviolet lithography) to enter Chinese mainland. Sk Hynix originally hoped to improve the production efficiency of memory chips through this equipment < p > in response to this matter, Dai Qi, the US trade representative, said when participating in a radio program recorded in advance by South Korean CBS Radio and broadcast on November 22 that the US move was out of "reasonable concern" that if these cutting-edge equipment were introduced into China, it might bring risks to us national security, and revealed that there might be more such measures in the future According to Yonhap's report on November 22, Dai Qi paid a four-day visit to South Korea from last Thursday (November 18). She made the above remarks in an interview with South Korean CBS Radio < p > "I know that the technology involved in this issue is highly sensitive, and people have reasonable concerns that the development of this technology may bring risks to national security," Dai Qi said < p > with regard to the view of the outside world that "the ROK's position is awkward between China and the United States", Dai Qi claimed that she knows the difficulties of the ROK and learned about the situation during her visit to the ROK, but everyone lives in the era of economic integration and needs to work together to solve the challenging issues < p > at the same time, she also shouted to South Korea: "it is very important for us to cooperate with our partners and allies on common economic and national security issues. I would like to reiterate that we think South Korea is one of our most important national security partners." < / P > < p > when asked whether there are other projects that will be subject to such "supervision" in the future, Dai Qi said: "Yes, on issues related to national security. National security includes military and defense concerns, but it can also be broader." < / P > < p > it is reported that for the "Indian Pacific economic framework" of US President Biden Whether China will be ruled out or not, Dai Qi said that the framework is an independent channel from China, but she denied that the United States will create a new economic alliance that will exclude China. She said that the US China relationship is very special and full of uncertainty, so it is necessary to adopt targeted contact strategies according to different partner countries. < / P > < p > Dai Qi delivered a speech during her visit to South Korea from the US media < / P >< P> China's Chinese mainland Wuxi has introduced three SK people to Holland, which is planning to upgrade its storage chip production facilities in China's factory in Wuxi. The process requires the use of EUV lithography produced by ASMA, Holland, which has been opposed to the idea that the advanced tools are used to strengthen the military strength of the Chinese mainland. < / P > < p > however, this plant in Wuxi is crucial to the global electronics industry because it produces about half of SK Hynix's dynamic random access memory chips (DRAM) IDC, the market analysis company, said that the demand for global memory market will grow by 19% in 2021 alone. A senior White House official refused to comment on whether the US side would allow SK Hynix to bring EUV lithography to Chinese mainland, but the official told Reuters that the Biden administration still focused on the 15%, the company said in 2021. To prevent Chinese mainland from developing the most advanced semiconductor manufacturing by using the technology of the United States and allied countries, this will help the military modernization of Chinese mainland. On

11 21, observer network contacted ASMA on the matter, and said: no further information can be provided, nor does the company comment on the specific affairs of a single customer. SK Hynix also has not responded to the observer network. The Yonhap reported that in response to the matter, SK Hynix CEO Li Xixi said: "we will cooperate with stakeholders and make wise response measures." < / P > < p > asmai nxe3400 EUV lithography machine figure from asmai's official website < / P > < p > Yonhap also mentioned that in order to solve the problem of chip shortage, in September this year, the U.S. government asked major semiconductor enterprises and automobile enterprises in the world to provide trade secret information, while Samsung Electronics and SK Hynix in South Korea submitted their "business information" in early November < / P > < p > the US government once claimed that the process was "voluntary", but also revealed that there were tools for these enterprises to submit such information when necessary. Earlier, Gina Raimondo, US Secretary of Commerce, said that under the "unprecedented" situation of global supply chain shortage, this requirement was "inevitable" In an interview with South Korean CBS Radio, Dai Qi also talked about this topic, saying that the United States would cooperate with South Korea to meet the challenges of the global supply chain, especially in the semiconductor field. When asked whether this was a "one-time event", she expressed "optimism" and said that the two countries (the United States and South Korea) had "opportunities and tools to solve bigger problems" < / P > < p > "the requirement to submit information is part of the U.S. government's efforts to identify bottlenecks, because our partners in the industry and government channels have shared information with us, and we also feel that there is an information gap in the supply chain in areas such as production and customer base," said Dai Qi
