US President Donald Trump on Saturday invited Philippine President Rodrigo Duterte to Washington in a "friendly" call, in which the leaders discussed the "threat" of North Korea, the White House said.
"It was a very friendly conversation, in which the two leaders discussed the concerns of the Association of Southeast Asian Nations (ASEAN) regarding regional security, including the threat posed by North Korea," the statement said.
The leaders also "discussed the fact that the Philippine government is fighting very hard to rid its country of drugs, a scourge that affects many countries throughout the world."
