President Donald Trump has arrived in the Philippines to attend a pair of international summits and close his five-country tour of Asia.

Trump is slated to meet several times with Philippine President Rodrigo Duterte (doo-TEHR’-tay). Duterte has come under intense criticism from human rights advocates for overseeing a violent drug crackdown that includes extrajudicial killings. Trump has previously praised Duterte’s handling of his nation’s drug problems.

Trump was originally scheduled to depart Manila on Monday but he added a day to the visit so he could more fully participate in one of the summits.

Trump also visited Japan, South Korea and China.

Trump said during a news conference Sunday in Vietnam that he believes U.S. intelligence agencies, which have concluded Russia interfered in the 2016 U.S. presidential election to help him win.

But Trump also says he believes Russian President Vladimir Putin when Putin claims his country did no such thing.

Duterte has come under fierce criticism from human rights groups for overseeing a violent drug war complete with extrajudicial killings .
