Billionaire hedge fund manager William Ackman, whose investment assets have shrunk by more than half in the last three years, has made a second round of staff cuts and laid off three investor relations team members, two sources familiar with the matter said on Tuesday.

The prominent manager cut one investor relations executive and two investor services executives at his New York-based Pershing Square Capital Management hedge fund last week, the sources said. These layoffs come after Ackman cut his staff by 10 people in January, shrinking the firm to 46 employees from 56.

A state-supported Chinese paper suggested how local business handle tariffs. The Global Times’ editors wrote:

Trade frictions between China and the US continue to escalate. Now, it’s time for China to take further self-defense measures including offering fair subsidies for the companies and industries that may suffer great losses due to unfair actions taken by the US.

The ongoing trade tensions are now spilling over into the technology sector as media reports said US President Donald Trump plans to bar Chinese companies from investing in key technologies in the US. Although Peter Navarro, one of Trump’s top trade advisors, was quoted by US business channel CNBC as saying that there “were no plans to impose investment restrictions,” we cannot rule out the possibility that Chinese technology companies may still be treated unfairly and thus become the victims of Trump’s trade war.
