When it comes to diplomacy, Donald Trump is not afraid to pull out the big guns.

Visiting China on a state visit to boost trade relations and contain the crisis with North Korea, the US president called upon his six-year-old granddaughter to help smooth the path.

Guests at a state dinner in Beijing last night applauded politely as Arabella Kushner, whose parents are the president’s daughter Ivanka and her husband Jared Kushner, performed a traditional Chinese song on a large video screen.

The pre-recorded clip, which shows the youngster singing and reciting poems in Mandarin, garnered more than 30,000 likes and 5,000 comments in just 24 hours after it was shared on Chinese social media, according to The Times.

Viewers see her dressed in Chinese attire in front of the American flag for the performance, which she dedicated to the Chinese leader and his wife, who she refers to as Grandpa Xi and Grandma Peng.

It is not the first time that the First Granddaughter has been cast into the media spotlight for her proficiency in Mandarin. Earlier this year she and her mother attended Chinese New Year celebrations at the country’s embassy in America.

Later that day, Ivanka posted a video on Instagram of Arabella singing in Mandarin, together with a message for the New Year.

And when the Chinese premier and his wife Peng Liyuan visited Mr Trump’s Mar-a-Lago estate in Florida back in April, she was called upon to show off her talent once again.

Arabella is reported to have been learning the language from her Chinese nanny since she was just 18 months. This year’s New Year greeting was the third that she has recorded.

Her most recent offering featured a children’s song about sweeping rice fields, a jade-green river and a lake studded with lotus flowers. She also recited an ancient text used to teach children the values of Confucianism, as well as another song and two poems.
