In recent days the Trump administration has approved a USD 1.4 billion arms sale to Taiwan and blacklisted a small Chinese bank over its business ties with North Korea.
In addition, the State Department has given Beijing a dismal grade in a new human trafficking report.
American officials had been describing improved coordination with China as the centerpiece of their North Korea strategy. They seek to prevent the North from being ableto strike the US homeland with nuclear weapons.
