Filipino president Rodrigo Duterte is never shy about commenting on his fellow world leaders, whether he's calling the top brass at the UN "stupid" or labelling Barack Obama a "son of a b*tch".
Now it appears that Duterte, who has even likened himself to Adolf Hitler, has targeted North Korea.
The outspoken Filipino president gave a speech only days before he's due to host the Association of Southeast Asian Nations (ASEAN) Regional Forum.
In it, he claimed North Korea's desire was to "end the world" and personally attacked the regime's leader.
He called Kim Jong-un a "son of a b****" with a "chubby face" and claimed the North Korean leader was playing dangerous games.
Donald Trump recently told Duterte he was doing a great job, and said they were fairly similar as leaders. Given that the US has a mutual defence treaty with the Philippines, perhaps Trump won't be so happy about his Filipino counterpart's latest comments.
