The Trump administration has pitched several other countries on its view that the global asylum system has been rampantly abused and urged them to join the United States in cracking down on such migration. Deputy Secretary of State Christopher Landau led the discussion on Thursday on the sidelines of the U.N. General Assembly alongside representatives from Kosovo, Bangladesh, Liberia and Panama. Landau’s gathering allowed American officials to gauge early support and interest in what could be a massive overhaul of the asylum system that has been in effect since World War II. Human rights groups watched from the sidelines with unease.
