The promo features Rihanna dressed as a "gangster goth geisha".
Speaking about the track last year, Martin said he thought 'Princess of China' was the highlight of Mylo Xyloto, adding that he had penned the track with Rihanna in mind.
He explained: "We had a song that I'd secretly kind of written to see if Rihanna would want to sing it. And then the rest of the band wanted to keep it, so we came up with the idea of asking her to sing it with us, and, to our great surprise, she said okay."
Martin also stated last year that this will be the band's last collaboration.
