Tthe Biden administration has unilaterally severed China’s access to high-end computer chips, or semiconductors. Given that chips are now strategically more important than oil, the move has been described as nothing less than a declaration of economic war.
This smokeless war between the US and China, and why China can’t produce its own advanced chips despite its trillion yuan investment, is the subject of Chris Miller's new book "Chip War".
All I can give you of this recently released book is this preview, but you can read online "The Chip War" by Fred Warshofsky, published as long ago as 1989, so there's nothing new here except that it has become even more critical now because the West's lead in this area is under threat.
