KEY POINTS
  • Mexico expelled its North Korean ambassador Thursday
  • The move unusually aligned it with Washington's stance
  • Mexico has traditionally sought to steer clear of diplomatic ructions

The Mexican government on Thursday said it had declared the North Korean ambassador to Mexico persona non grata in protest at the country's nuclear tests, an unusually firm step that moved it closely into line with Washington.

In a statement, the government said it had given Kim Hyong Gil 72 hours to leave Mexico in order to express its "absolute rejection" of North Korea's recent nuclear activity, describing it as a grave threat to the region and the world.
