"Gathering with decision-makers from all walks of life and creating a judgement-free space to share ideas, offer different perspectives, and tell stories helps us to reconnect with why this work is so important.
"We hope that connections made between leaders will spark new thinking and action to uncover and stamp out all forms of forced labour."
Her visit coincides with her cousin Prince Harry, who is also in New York as part of Climate Week.
