"Threatening and destabilising actions only increase the North Korean regime's isolation in the region and among all nations of the world. All options are on the table," he said.
In a statement, the US president said, "The world has received North Korea's latest message loud and clear: this regime has signalled its contempt for its neighbours, for all members of the United Nations, and for minimum standards of acceptable international behaviour."
Earlier, he spoke with Japanese Prime Minister Shinzo Abe to address North Korea's launch of a missile that overflew Japanese territory, the White House said.
"The two leaders agreed that North Korea poses a grave and growing direct threat to the United States, Japan, and the Republic of Korea, as well as to countries around the world," it said.
Trump and Abe committed to increasing pressure on North Korea, and doing their utmost to convince the international community to do the same, the White House added.
