Amid growing technological rivalry between the United States and China, it has emerged that the US is stepping up its efforts to hinder China's technological development, especially in the semiconductor industry, for national security reasons. To do so, the US is reportedly seeking collaboration with Japan, a leader in the production of chips and electronic components.

The US move has raised concerns among Japanese companies, who fear possible retaliation from China in their key technology sector. Chipmakers in Japan are aware that any action that harms China could have negative repercussions in their own market, as the Asian giant is one of their main buyers.

Japan's dependence on China for exports of chips and electronic components means that any move against the Asian country could have a significant impact on the Japanese economy. Japanese companies are therefore in a delicate position as they must balance their commercial interests with political pressures from the United States.

Faced with this situation, the Japanese government has expressed concern about the possible repercussions of joining the United States in its confrontation with China in the chip war. Japan seeks to maintain a neutral position and preserve its trade relations with both countries, avoiding being dragged into a technological conflict that could seriously affect its economy.
