After Philippine President Rodrigo Duterte reacted aggressively on US President Barack Obama’s intervention into his controversial attitude towards drug dealing, the White House canceled the meeting scheduled between the two on Tuesday.

Duterte not only called for a press conference where he said that Obama should have been more respectful in mentioning the drug dealing policy that he has initiated but he also used slang language to address the latter. “Who does he think he is? I am no American puppet. I am the president of a sovereign country and I am not answerable to anyone except the Filipino people,” Duterte said on Monday. “Son of a b****, I will swear at you.”

Both leaders had been ready to meet in the Association of Southeast Asian Nations summit in Laos on Tuesday. Obama was already there meeting the Southeast Asian head of state.

Before the meeting, the White House revealed that the US leader would talk to his Filipino counterpart regarding his way of tackling drug dealers. He would emphasize extrajudicial killings or on-the-spot government executions without judicial involvement.

Prior to landing to Laos, a reporter asked Duterte how he would face Obama’s questions on extrajudicial killings in the Philippines. To the question, the firebrand leader said that he expected the US president to be “respectful” in addressing the issue. He called Obama the “son of a whore” whom the Philippines will be “wallowing in the mud like pigs if you do that to me.”

In his media conference, as CNN reported, Duterte blames the United Stated for the unrest on the island of Mindanao situated in southern Philippines. This was because the nation invaded the Philippines and converted the public into “subjugated” masses.

Obama responded to what Duterte said at the end of a G20 summit held in Hangzhou, the eastern Chinese city.  “What I’ve instructed my team to do is to talk to their Philippine counterparts to find out if this is in fact a time when we can have some constructive, productive conversations,” Obama said.

“Obviously, the Filipino people are some of our closest friends and allies and the Philippines is a treaty ally of ours. But I always want to make sure that if I’m having a meeting that it’s actually productive and we’re getting something done.”
