The US and China are working on a "range of options" on North Korea as tensions mount over the country's nuclear and missile programmes.
A top US security adviser told ABC News there was consensus with China that this was a situation that "could not continue".
The comments come after a failed missile test launch by North Korea and a massive military parade.
President Trump had earlier said China was "working with us" on the issue.
Beijing, Pyongyang's biggest ally, has come under pressure from Washington to exert more pressure on its neighbour.
