It comes after Kim Jong-un’s regime launched what it claimed was an intercontinental ballistic missile, capable of reaching the West coast of America.
The regime has also conducted several underground tests of atom bombs, although it is not known if it has succeeded in shrinking the device to a size that could be carried on a missile.
Last week America’s UN ambassador Nikki Haley said Washington was prepared to use the full range of its capabilities to defend itself and its allies from a threat coming from North Korea’s missile and nuclear programs.
The US diplomat did not rule out the use of military force if necessary.
Mr Trump has launched a global campaign to tackle the North Korean threat and last week urged Kim’s ally China to apply pressure over his nuclear programme.
