President Doland Trump invited Philippine leader Rodrigo Duterte to the White House during what administration officials referred to as a "very friendly" call.
During Saturday's call, Trump expressed the nation's commitment to developing "a warm, working relationship" with the controversial leader.
"The discussion that transpired between the presidents was warm, with President Trump expressing his understanding and appreciation of the challenges facing the Philippine president, especially on the matter of dangerous drugs," presidential spokesman Ernie Abella said in a statement.
Duterte has been widely criticized for escalating the war on drugs in the Philippines after taking office in June 2016. Approximately 7,000 people have died as part of his crackdown on drugs, NBC reports citing Human Rights Watch.
Relations between the Philippines and the U.S. became strained under Obama, who Duterte said could "go to hell."
White House Chief of Staff Reince Priebus defended Trump's decision to pursue friendlier relations with the Philippines despite the leader's human right's record.
Priebus stressed the importance of working with allies in the Pacific, amid threats of an attack from North Korea.
"It doesn't mean that human rights don't matter, but what it does mean is that the issues facing us developing out of North Korea are so serious that we need cooperation at some level with as many partners in the area as we can get to make sure we have our ducks in a row," Priebus said in an interview on ABC's "This Week."
