Analysts warn that Trump will probably demand more action from Mexico to counter drug-trafficking groups

Mexico’s president Claudia Sheinbaum has defended the latest transfer of 37 Mexican cartel operatives to the US as a “sovereign decision”, as her government strives to alleviate pressure from the Trump administration to do more against drug-trafficking groups.

It was the third such flight in the year since Donald Trump returned to the White House, but analysts warn that while it remains an effective pressure valve, the returns may be diminishing.
