Trump criticises S Korea and movie that won Oscar

US President Donald Trump took another dig at South Korea's Oscar-winning "Parasite" during a rally in Nevada on Friday night.

He said the East Asian country was not only "killing (the US) on trade", but had also "(won) the Academy Award for a fricking movie."

"Parasite" was named best picture, the first non-English-language film to get the top honour.

Trump's comments come a day after he spoke about the same film during a campaign rally in Colorado Springs.

"We've got enough problems with South Korea with trade. On top of that, they give them best movie of the year. Was it good? I don't know," he said on Thursday night.

"Parasite'" tells the story of how a family of four poor, unemployed people living in a slum basement apartment comically infiltrates a wealthy family residing at a luxurious mansion before things unravel violently and tragically.

The movie made history on 9 February, becoming the first South Korean film to win in the international film category, and the first foreign language film to win best picture.
