President Moon Jae-in's Southeast Asia trip was riddled with gaffes big and small.

In Malaysia, Moon was caught in a language slip during a summit and dinner with Prime Minister Mahathir Mohamad, when he offered an evening greeting in Bahasa in the afternoon and vice versa in a clumsy attempt to endear himself to his hosts.

In Brunei, during a dinner hosted by Sultan Hassanal Bolkiah, Moon proposed a toast that apparently offended some pious guests in the strictly dry Muslim country.

Some Bruneian officials apparently refused to respond to Moon's toast, while others even tried to stop the Korean guests from joining in. But a Cheong Wa Dae official said the toast had been "agreed by both sides in advance."
