Donald Trump has taken to Twitter to accuse China of "stealing" a US Navy drone.

But his tweet, sent before the sun was up on Saturday morning (US time), has seen him ridiculed for an unpresidential typo.

"China steals United States Navy research drone in international waters - rips it out of water and takes it to China in unpresidented act," the US President-elect wrote.

It took him a full hour-and-a-half to delete the tweet, replacing it with the correct spelling.

Writer and US political commentator Keith Olbermann said it was an "organic, Orwellian" phrase that could come to describe Mr Trump himself.

Another called it "the most perfect Freudian slip of all-time", while Harry Potter author JK Rowling even cracked a joke at his expense.

It's believed Mr Trump wrote the tweet himself. He's said in the past he dictates tweets to "young ladies" during the day, but does it himself after-hours.

Mr Trump was referring to China's seizure of an underwater drone vessel in the South China Sea on Thursday. China has said it will return the drone, which the US says was collecting information about the water.
