Citing bruising reprimands from Washington, Philippine President Rodrigo Duterte said Sunday he may pursue new alliances with Russia and China after those nations urged him to turn away from the U.S.

Duterte threatened to tear up a historic agreement that has seen the U.S. send troops and military hardware to the Philippines. He called the 2014 document a mere executive agreement that can be cast aside as it was drafted by a previous administration.

"Tomorrow I will be friends with (Russian President Vladimir) Putin and (Chinese President) Xi Jinping," the Philippine Daily Inquirer reported Duterte as telling an audience in the Philippine city of Bacolod.
