Pinning the tweet to the top of her page, she wrote: 'Those who say it cannot be done, should not interrupt those doing it.' - Chinese Proverb'. A pseudo-Confucian version was fabricated in 1962 - perhaps explaining why Ms Trump believed it was a Chinese proverb.
Countless Twitter users claimed the proverb was not Chinese, while a number of experts told The Independent there was no evidence the proverb had originated in China.
People on the popular Chinese social media platform Weibo attempted to come up with a list of real Chinese proverbs that might match what Trump was trying to say.
The historic meeting between Donald Trump and Kim Jong-un took place on Tuesday in Singapore.
Larry Herzberg, a professor of Chinese at Calvin College in MI, said Ivanka's tweet was "yet one more example of Americans ascribing a quote to the Chinese, often to Confucius, when they don't really know the origin of the saying". It was molded over the years to its current form, the quote-focused website found, at one point being attributed to Irish playwright George Bernard Shaw.
"[My editor] really can't think of what exactly this proverb is".
As first daughter and a senior adviser to her father, Ivanka has frequently emphasised her connection to China and Chinese culture. "Please help!", read a post by news channel Sina, which is Weibo's parent company, as per news agency AFP.
The ridicule was present stateside, too, where conservative writer and ardent Trump critic Bill Kristol lambasted her over the proverb.
Weibo users quickly piled in to mock the President' daughter.
One person wrote: 'She saw it in a fortune cookie at Panda Express, ' while another added: 'It makes sense, but I still don't know which proverb it is'. "It seems in fact to be American from the turn of the 20th c. -which makes sense, since its spirit is can-do Americanism", he tweeted.
She also wrongly attributed a quote to Albert Einstein in July a year ago, writing: "If the facts don't fit the theory, change the facts".
'But why are Trump WH (White House) aides giving our proverbs to China, increasing our proverb deficit?' he quipped.
