In U.S.-China Tech Feud, Taiwan Feels Heat From Both Sides

TAINAN, Taiwan — The United States and China are wrestling to lead the world in artificial intelligence, 5G wireless and other cutting-edge technologies. But the real wizardry that makes those advancements possible is being performed on a yam-shaped island that sits between them, geographically and politically.

On Taiwan’s southern rim, inside an arena-size facility stretched out among lush greenery and coconut palms, colossal machines are manipulating matter at unimaginably tiny scale. A powerful laser vaporizes droplets of molten tin, causing them to emit ultraviolet light. Mirrors focus the light into a beam, which draws features into a silicon wafer with the precision, as one researcher put it, “equivalent to shooting an arrow from Earth to hit an apple placed on the moon.”

The high-performance computer chips that emerge from this process go into the brains of the latest tech products from both sides of the Pacific. Or at least they

TikTok Deal with Oracle and Walmart Trips Over U.S.-China Feud

WASHINGTON — A deal intended to address the Trump administration’s concerns about TikTok’s ties to China was complicated on Monday by a disagreement over whether a U.S. company would control the social media app and the president’s threat to block any agreement that leaves the service in the hands of a Chinese company.

ByteDance said it would hold a majority share of the new company until it went public within the next year. Oracle said on Monday that as soon as the new company, TikTok Global, was created, ByteDance would lose its ownership stake in the service.
