BlackRock, the world's largest asset manager, is tightening its rules for employees traveling to China, banning work-related use of company devices like phones and laptops during trips, according to a Bloomberg report. The move appears to be a security precaution, likely reflecting growing corporate caution around data risks in China.

Editor’s Note: This isn’t just about BlackRock—it’s another sign of how businesses are adjusting to geopolitical tensions, especially around tech and data. When a financial giant starts treating China trips like a security risk, it hints at broader unease in global boardrooms. Expect more firms to follow suit.
