China Bans U.S. Chipmaker Micron's Products, Escalating Tech Battle With United States

China's cybersecurity regulator has found that Micron Technology's products have failed its network security review and banned Chinese firms from buying chips from the U.S. memory manufacturer.
The ban comes after China announced a review of Micron imports in late March in a move that was seen as retaliation for sanctions Washington has imposed on Chinese chipmakers in recent years.
Micron is the first US chipmaker to be targeted by Beijing after a series of export controls by Washington on certain US components and chipmaking tools to block them from being used to advance China’s military capabilities.
The move shows how far apart the two sides are drifting on tech policy and is seen as a reprisal for the Biden administration's harsh steps to block Chinese chip makers' access to crucial tools.
South Korea's companies, Samsung and SK Hynix, have the most to gain from the Micron ban and may not follow the United States' lead in harming their own interests.
