BEIJING: China's government appealed to Japan on Monday not to disrupt the semiconductor industry after curbs on exports of Japanese chip-making technology took effect, adding to technology restrictions Washington and its allies have imposed on China on security grounds.

The Japanese restrictions that took effect Sunday limit Chinese access to tools for etching microscopically small circuits on advanced chips for smartphones, artificial intelligence and other applications. The Netherlands also joined the United States in limiting access to chip-making tools that Washington says could be used to develop weapons.
